Beth Slocum (Plaza) dies after getting bitten by a venomous snake, leaving her boyfriend Zach Orfman (DeHaan) devastated. Zach starts spending time with Beth's parents Maury (Reilly) and Geenie (Shannon), up until the moment where they suddenly shun him out. Curious, he comes to their home uninvited, only to find them in company of... a very much alive Beth, who seems to have forgotten everything since last week, including dumping Zach and dying.
Delighted, Zach sees this as a second chance for his relationship with Beth, but he soon realizes that his girlfriend Came Back Wrong, and she keeps getting worse...
This film contains examples of:
- Abhorrent Admirer: Beth becomes this to Zach in the second half of the movie.
- Attractive Zombie: Beth is this at first; however, she gradually turns into the usual Romero-escue carnivorous zombie.
- Came Back Wrong: Beth starts out as a Damaged Soul and slowly transitions into a Monster from Beyond the Veil as the movie progresses.
- Covert Pervert: Maury Slocum is revealed to be one shorty before he bites the dust.
- Dying as Yourself: Before shooting a feral, growling Beth, Zach tells her he loves her. She manages to answer that she loves him too in her human voice.
- Famous Last Words: Their significance (or rather lack thereof) is discussed in-universe by Zach and Maury.
- Go Mad from the Revelation: Beth, who was already not herself up until that point, does not take the revelation that she's a zombie lightly: she assaults Zach, steals and crashes his car, and later on starts mumbling a Madness Mantra and kills a guy.
- I Want You to Meet an Old Friend of Mine:
- The Jaywalking Dead: Zach accidentally runs over Beth with his car. She doesn't seem to be worse-for-wear after the accident.
- Madness Mantra: After Beth is told she's a zombie, she spends several scenes continuously mumbling "I'm dead, I'm alive, I'm dead, I'm alive..."
- Our Zombies Are Different: In this movie, zombies start out with their human personalities, but as their brains decay, they become first absent-minded and forgetful, then increasingly erratic and aggressive, and only after a certain point they finally become the familiar growling zombies we know and love. They also have a bizarre fondness for attics, and smooth jazz calms them down. And the biggest difference, which could play a part in how quickly this particular Zombie Apocalypse is dealt with: they are not contagious.
- Pun-Based Title: Obviously a play on "life after death".
- Soundtrack Dissonance: Due to the zombies' appreciation of smooth jazz, it starts playing pretty much everywhere at some point. Some of the more gruesome scenes in the movie are set to it.
- Zombie Apocalypse: Starts without any explanation, appears to be a localized one, and is quickly dealt with.
