Life After Beth (2014)

Zach Orfman is devastated when his girlfriend, Beth Slocum, dies after being bitten by a venomous snake while hiking. He begins spending time with Beth's parents, Geenie and Maury; when Zach confesses that he and Beth were having problems in their relationship, Maury tries to brush it off.

When Geenie and Maury suddenly stop contacting Zach, he visits their house and sees Beth through a window. Zach yells to be let in but his brother Kyle, a security officer, escorts him off the premises. Zach breaks in to the Slocum's that night and discovers that Beth has risen from the dead and her parents have been hiding her. He begins having arguments with Geenie and Maury about Beth. They are reluctant to let her leave the house during daytime and refuse to tell her that she died. When Zach takes Beth on a daytime date in the park, her face starts to blister and Maury bans Zach from seeing Beth. Zach continues to sneak in.

Beth grows increasingly violent and begins having severe mood swings. Zach notices other people around town acting similarly and tries to sort out his thoughts by talking to childhood friend, Erica Wexler. As they leave the diner, Zach accidentally runs Beth over with his car. Unharmed, she scares helpful bystanders away by screaming at them. After a violent confrontation with Erica, when Beth mistakenly assumes Zach is cheating on her, Zach brings Beth to her grave and tells her the truth. Zach tries to break up with her, only for her to angrily drive off in his car.

Maury implores Zach to tell Beth that he lied about her being dead and promise to stay with her forever, to which Zach reluctantly agrees, noticing that Beth's emotional stability slows her zombie behavior. He tries to run away with her, wanting to avoid the growing problems with the town, which also agitate Beth, but Maury knocks him out to take Beth home. Once Zach wakes, he returns home to find burnt bodies in the backyard, which he believes to be his family.

Zach prepares to leave the state, but changes his mind and drives back to the Slocum house. He finds the house in disarray and discovers that Beth, now a full-fledged bloodthirsty zombie, has eaten Maury and some of Geenie's fingers. Zach enables Geenie to escape and calms Beth by promising to hike with her. They run into Kyle, who is hunting zombies and explains that their parents are still alive and have fled to a safehouse. Kyle gives Zach his handgun and encourages him to put Beth out of her misery. Zach and Beth stop by a cliff. He tearfully apologizes for never doing the things she wanted when she was still alive. They profess their love to each other before Zach shoots her in the head.

Zach is reunited with his family at the safehouse, along with a traumatized Erica, who was forced to kill her own grandmother. The survivors make plans to leave town, but the power suddenly returns and a TV news report claims things have returned to normal. Some time later, Zach visits Beth and Maury's graves. Zach invites Erica for dinner and she accepts, smiling as they drive off.
