A young man's recently deceased girlfriend mysteriously returns from the dead, but he slowly realizes she is not the way he remembered her.

A hike alone in the woods ends tragically for Beth Slocum with a fatal snake bite. Her death leaves her parents and boyfriend Zach reeling. After the funeral, Zach tries to make friends with Mr. and Mrs. Slocum, but even they reject him, and he's determined to figure out why. Then he sees Beth.

Her parents are trying to keep her resurrection a secret, but zombie Beth provides Zach with the opportunity to do everything with her that he didn't get to do while she was still alive. But with Beth's increasingly erratic behavior and even more strange occurrences around town, life with the undead Beth proves to be particularly complicated for her still-living loved ones.
