A doctor named Bill Rand is walking home one night when a living shadow man beats him up and stabs him to death.
Next morning, Jess and Nathan meet up and talk. Their talk is put on hold when Audrey calls him about the murder so he goes to the site. Nathan admits that he's still very nervous about his relationship with Jess. They examine the body and figure that he was beaten up by something with superhuman strength. Bill worked at Hessberg Medical Center, where Jess has recently gotten a job as a caretaker.
As they enter the medical center, Nathan teases Audrey about how she can't remember the other officers' names. Indignant, she tries to list their names, but gets a lot of them wrong. Dr. Wilson says that some people claim that the Dark Man has been killing doctors and patients. Jess is doing grief counseling. Thornton Aarons, a blind man, talks about his dead wife Sarabeth. The other patients also claim the Dark Man was responsible for the killings.
They go back to the station to go over their limited information and Jess visits them. She kisses Nathan, who nervously backs away. Nathan asks her to stay away from the center, as it might get dangerous, but she refuses, dismissing the Dark Man as a superstition.
Dr. Wilson is at home talking with her husband when he leaves the room to cook. The shadow figure enters, flat against the wall, but becomes solid to impale both her and her couch with a shadow sword.
Nathan and Audrey examine the murder site and are baffled at how it could have happened, noting the impossible angle and how the wall is undamaged even though the couch was right next to it. They question several patients, but their descriptions of the Dark Man are all different (one describes him as tall, another short, etc).
They visit the Teagues and check their archives for similar incidents, but find nothing. Vince and Dave say that they've never heard of the Dark Man. Audrey suggests Nathan take a break and go out with Jess, but he insists on staying on the case. She demands to know what is the matter with him, and he explains that he doesn't think it can work out because he can't feel anything. Audrey orders him to at least try, and he finally agrees.
Later, the families of the Dark Man's victims are angry at Audrey for having their bodies exhumed. She replies that she's sorry but she is trying to find out how the Dark Man operates.
At Jess' house, she and Nathan have wine. He talks about how he can't feel. She kisses him, but he doesn't feel it. She tries again, urging him to feel it in his heart. He kisses her back.
The Teagues visit Audrey at the station when the Dark Man enters and attacks them with his sword. Dave takes a few pictures of him and the flashes briefly stun him, but he presses his attack. Audrey realizes that he can't exist without light and starts turning off all the lights, but the Dark Man guards the remaining light source.
Nathan and Jess are about to have sex when his cellphone rings. She says to ignore it, but he answers. Audrey tells him what is happening and he rushes to the station. He shoots out the remaining light, and the Dark Man disappears. They realize everyone described him differently because he changed shape depending on the light. Audrey apologizes for ruining Nathan's date.
The next morning, Jess talks with Thornton and he talks about how Sarabeth died when her chemotherapy failed.
Eleanor goes over the medical center's records and finds that none of the patients were properly given chemotherapy.
Jess goes over Thornton's medicine cabinet and finds a lot of unused pill bottles.
Nathan and Audrey look over Dave's photos and find that each flash destroyed a small part of the Dark Man's body. They then find evidence that Rand and Wilson had been selling chemotherapy drugs for money instead of administering them to their patients.
Thornton tells Jess that he keeps Sarabeth's old medications for their sentimental value. She leaves, taking two of the bottles.
The officers figure that the Dark Man killed the two doctors after he learned of their crime. Audrey wonders why he attacked her. Jess calls about the medication and says she has figured on her own that the patients were not really getting chemotherapy drugs. Nathan figures that she is in danger and rushes over to her house.
Thornton realizes that Jess stole two bottles and becomes enraged.
The Dark Man enters Jess' house and attacks her. Nathan and Audrey show up and the Dark Man leaves. Jess was knocked unconscious.
Nathan is very upset about his girlfriend almost getting killed, and Audrey urges him to calm down and look at the case rationally. Their only lead now is Thornton. They visit him in the medical center and find that he doesn't have a shadow. They realize that the Dark Man is his shadow, and that the Dark Man's sword is the shadow of his cane.
They find that Thornton doesn't know about the Dark Man, but Audrey gets an idea, urging Nathan to not do anything stupid. She tells Thornton that the people responsible for all the deaths are being held at the station's interrogation room, then drives back there.
Audrey puts two target silhouettes in chairs and waits. Nathan tells Thornton what they know and Thornton realizes with dread that the Dark Man targets people after he becomes angry at them. He begs forgiveness for the attack on Jess and asks Nathan to kill him, hoping the Dark Man will die as well. Nathan says he's thinking about it.
The Dark Man appears in the interrogation room and attacks the silhouettes. Audrey shines some heavy-duty lights on him and he disintegrates. Thornton's shadow reappears. Nathan says that he promised Audrey he wouldn't kill him.
The next day, Nathan comes to see Jess, but she says that she's breaking up with him and moving to Montreal. She can't handle the Troubles anymore after she almost got killed. She kisses him goodbye and leaves.
Audrey and Nathan put a sign on a door that says that the occupant must not be disturbed. By keeping Thornton in a pitch black environment, the Dark Man cannot exist, as without light, there can't be any shadows. Nathan is depressed and tells Audrey about the break up. Audrey says that she's there for him if he ever needs a shoulder to lean on and kisses him on the cheek. Nathan goes wide-eyed. As Audrey walks away, Nathan stares at her and puts his hand over the spot she kissed. He felt it.
- Accidental Misnaming: The Running Gag of the episode is that Audrey can't remember the names of her fellow officers, and she substitutes whatever comes to mind.Audrey (to photographer): Hey, can you make sure to get a picture of the back of the couch? Thanks, Tony.Photographer: (leaves, annoyed)Audrey (to Nathan): Steve?Nathan: Eddie.Audrey: Eddie? Damn. That wasn't even an option.
- Anywhere but Their Lips: Audrey gives Nathan a kiss on the cheek, much to his surprise. For multiple reasons.
- Bad Date: Not bad, just awkward, since Nathan is so tense and nervous. It gets better. And then worse.
- Cardboard Pal: Audrey tells Thornton, whose Trouble creates a murderous shadow, that they have two suspects in custody responsible for withholding his wife's chemotherapy medication. When Audrey goes back to the station, the "suspects" in the interrogation room are two target practice cut-outs.
- Casts No Shadow: How Audrey and Nathan figure out the Dark Man shadow belongs to Thornton.
- Fighting a Shadow: Thornton's Trouble is his shadow, which attacks people he feels are either responsible for his wife's death or are involved in investigating it.
- First Time Feeling: While it's not the very first time, Audrey's kiss is the first thing Nathan's been able to feel in quite awhile (the timeline is unclear) and he is thrown by it.
- Friendship Moment: Audrey and Nathan have one at the end, when he tells her about Jess leaving. Audrey claims him as her friend, and offers her friendship to him in return.
- Holding Both Sides of the Conversation: Audrey talks to the cardboard "suspects," holding a snarky conversation about the superficiality of adult friendships—a clapback against Nathan's teasing earlier in the episode about her having no friends and being unable to remember people's names.
- Hates Small Talk: Audrey dislikes this part of making friends.Audrey (to cut-outs): Would you like to go for coffee? Great! And then you can tell me about your brilliant kids, and I can pretend to be interested, and then I'll tell you about my something that I read, and then pretty soon, I'll just want to freaking kill myself.
- Indy Ploy: When the Dark Man invades the police precinct, Audrey tells Dave and Vince to turn out the lights, because you can't have a shadow without light. When Dave asks how she knows that this will work with this particular shadow, Audrey admits she's just making it up as she goes along.
- Interrupted Intimacy: Audrey is the cause, and feels bad about it.
- Love Cannot Overcome: Jess leaves Haven and breaks up with Nathan, because she cannot deal with the Troubles and his connection to them after being attacked.
- Medication Tampering: Rand and Wilson were withholding chemotherapy medication and selling it to other clinics, which led to the rapid death of Thornton's wife. This starts his Trouble, which proceeds to exact fatal retribution, although he does not appear to be aware that his shadow is actually killing people.
- Meaningful Echo: An interesting nonverbal variant, crossed with an Ironic Echo. When Jess drops off the Chinese food at the precinct, she kisses Nathan on the cheek by way of greeting. His response is stilted and awkward, and she apologizes for it. This is juxtaposed with Audrey kissing him on the cheek at the end of the episode, which isn't awkward at all—and not just because he can actually feel it.
- Monochrome Casting: Lampshaded when Audrey looks through old Herald microfiche looking for references to the "dark man" and finds an article about the first Black man to move to Haven.
- Open Mouth, Insert Foot: Jess drops by the station and brings Chinese food when Nathan and Audrey are working late. Audrey expresses her gratitude by telling Nathan to marry Jess. She then laments she made the situation awkward. Which is okay, because Jess one-ups the awkwardness by saying she and Nathan would have to get to second base first.
- Paralyzing Fear of Sexuality: Nathan expresses his anxiety to Audrey about his burgeoning relationship with Jess, because he hasn't been intimate with anyone since his Trouble started. He doesn't get to really find out whether this fear is valid or not, as it never gets that far.
- Running Gag: Audrey can't remember any of her fellow officers' names and keeps getting them wrong. They kind of just go with it.
- Ship Tease: This episode marks the start of Audrey and Nathan's.
- Shout-Out
- The title references the song of the same name by Bill Withers.
- Stunned Silence: Nathan after Audrey kisses his cheek, because he can feel it and it's the first thing he's felt in awhile.

- You Need a Freaking Drink: Jess offers Nathan wine in the hopes he'll relax even a little.
