In this campy comedy, a group of stoners inhales more than they bargained for when they buy a vintage bong named EeBee from an ad in High Times magazine. They have no idea that the possessed pipe will slowly suck them into a horrifying surreal world. As the potheads fight for their lives, EeBee's former owner (Tommy Chong) -- the only person who understands the bong's power -- tries to rescue them.
