In their dilapidated church headquarters, a greatly diminished and dispirited cult awaits the sign to off themselves. Their hapless leader, Dave, concocts a plan: to quell infighting and give them purpose in life before their deaths, he fakes a prophecy instructing them to make a movie and share their story with the world.

There's just one problem: they don't know the first thing about film production. So they recruit a director, and in the production of the movie, the once-disparate cult members find a uniting purpose. But just as they hit their stride, Dave receives a true prophecy. It's time for them to "exit."
