Two stoners try to reverse the zombie curse they have unleashed on the world.

Ringo and Stash are two freegan artisanal paraphernalia crafters. When they obtain a cursed evil relic, they unwittingly create a series of bongs that turn the smokers into flesh-eating zombies. Upon learning this, they are in a race against time to track down the zombies and turn them back to human before they wreak havoc on the city. They do all of this while catching up on their favorite 1980s action TV show "Johnny Patel: Private Eye".
