When the Apocalypse actually happens and a billion people are raptured up to heaven, Lindsey (Kendrick) and her boyfriend Ben (Daley) are left behind in suburban Seattle. The young couple try their best to lead a normal life surrounded by talking locusts, blood rain showers, and pot-smoking wraiths. But when the Anti-Christ (Robinson) makes his home base in their neighborhood, Lindsey finds herself the object of his affection. With the help of her family, friends, and a lawn-mowing zombie neighbor, the young couple set off to stop the Anti-Christ from taking her as his bride… and just maybe, saving the world in the process.
