It’s Halloween time in LA again, the first responders are called out to numerous weird calls. Buck is back working at the 118 but under conditional terms, he tries to make amends with the team. Maddie is convinced that she needs to be the one to save one of her 911 calls.
The 118 are summoned to a corn field maze when two boys are attacked by crows after provoking them for their own amusement. Thanks to some ingenuity, they get the boys safely to the hospital, but one crow appears to have taken a shine to Chimney.
Buck returns to full duty at the station, but is given the cold shoulder by the rest of the house, sans Hen, because of his lawsuit he filed against Captain Nash, the LAFD, and the city, over being denied returning to full duty because of his injuries following the tsunami. He's told to stay at the house when they get another run.
Maddie helps the woman who called 911 previously get home safely due to a bad car, but while she's on the phone, Maddie does a little investigating due to her own past trauma with her own abusive husband, and even shares some things with the woman since they have a few things in common.
One night, a woman is driving along, but just after she finishes a phone call, she takes evasive action to avoid a couple of bicyclists, but ends up having one smash headlong into her windshield and get stuck there. She apparently takes no notice of what happened, having apparently bumped her head and dazed herself, and drives home as if nothing happened, parking in her garage and going inside, oblivious to the guy still being alive, but in serious pain from his wounds.
Maddie and Chimney are out and about when they run into the couple that Maddie was dealing with previously, and Chimney introduces himself to them, but they have to leave due to Chimney needing to work a shift the next day, which is Halloween. Chimney confronts Maddie about things, and she confesses about what happened, and Chimney brings up Maddie's ex Doug and she shouldn't lie about what she's doing, but when Maddie refuses to accept the truth, Chimney tells her off and leaves to get ready for work the next day.
Halloween arrives, and Nash has resigned Buck to giving out candy to trick-or-treaters to the firehouse as another punishment for his lawsuit against them. Chimney tries to provide some encouragement to Buck, and it seems to work, but Chimney is worried about Maddie after what happened. Then Chimney notices that the crow from before is back, but it is gone before Eddie sees it.
Back with the woman who hit the bicyclist, she's still in such a daze that she continues to be oblivious to his presence as she takes off to work, but a family at a taco joint sees the car and calls 911, and Maddie sends out an APB to the LAPD, but they are not sure if it is legit.
At Station 118, trick-or-treaters are collecting candy and Buck is passing out smoke detectors, and it seems Halloween is going fine, but at one house, the homeowner is meet by a young girl who appears to have escaped some sort of torture as she had a pair of handcuffs stuck to one wrist, and soon passes out in the owner's arms, causing him to have his wife call 911.
At the dispatch center, Maddie is off-duty and takes off, only to find Tara, the woman she was trying to help, confronting her for stalking her and filling a complaint against her. Maddie tries to explain the situation to her, but Tara was initially reluctant to cooperate, and tells Maddie to leave her and her husband alone before she storms out of the center, and Sue confronts Maddie about what she just saw.
Meanwhile, Athena is assigned the duty of finding out what happened to the girl that collapsed at the homeowner's house, and assigns her patrol officers to find a house that is not decorated for Halloween. Finding one herself that fits the bill, Athena goes to check it out. When there's no response at the door, she heads in the back, where upon finding a broken window and blood stains, she goes inside, and soon finds her way to the basement, finding many kids down there in a similar state to the one that was taken to the hospital, to her shock and horror. LAPD, LAFD, and Child Services are summoned to the scene, and when the couple who own the house and the children arrive, Athena furiously has them arrested for child abuse and hauled off in cuffs themselves.
At the 911 center, Sue confronts Maddie for the situation with Tara, and decides that, because of Maddie's actions, and her PTSD from Doug, Sue assigns her a psychological meeting, and suspends her from the floor until after it is done.
At the firehouse, Hen is watching the news about the couple that was arrested for child abuse, and discusses it with Nash, especially with Buck and how he's not taking things seriously in regards to the settlement he's getting from the city for his lawsuit. As for Buck, as Eddie is still giving him the cold shoulder over the lawsuit and reprimands him for his idiocy, not considering what it would do to the rest of the 118, Buck begins to realize how stupid he had been acting in a fit of anger over his job and tries to apologize, but Eddie is still not willing to forgive him, but then decides to do so, but warns him not to do it again. Nash then comes down and tells Buck to go home for the night as he earned it. As Buck stops by a gas station, he spots the dazed woman and her car with the guy stuck in the windshield, and immediately gives pursuit when she drives off. He calls into 911 to let them know, causing them to realize that the earlier call to Maddie was not a Halloween prank call, and Buck is forced to use his own car to stop her and confront her until the Rescue Ambulance arrives. However, while he was trying to help the wounded man, he injured himself in the process, and confesses to using blood thinners upon seeing how badly he was bleeding to the paramedics.
The next day, Maddie stops by the station to see Chimney over when he scolded her, and confesses that Tara figured out the truth and Maddie was nearly fired for it. Chimney assures her this was all due to her PTSD with Doug, and then the crow that Chimney kept seeing appears, and as it turns out, it was returning Chimney his nametag as he left it behind at his first call of the episode.
At Cedars-Sinai, Nash arrives to check on Buck, and he explains the whole situation to him, and Nash is impressed by Buck's heroism as he did what was natural for him by instinct as one of Los Angeles' Bravest. As a result, Nash allows Buck full return to duty, despite the circumstances, and the two of them head off to have breakfast together.
