Larry Cohen concocts this comedic horror-thriller involving an ex-FBI agent turned industrial spy hired by a desperate ice cream industry, trying to steal the secret formula from a corporation pushing a newly marketed yogurt-like food substance called The Stuff. He discovers the substance, which is found bubbling up from seemingly unlimited deposits underground, is deadly and humanity hangs in the balance. The Stuff is a delicious, no-calorie dessert that is highly addictive to all who eat it. So addictive that all people want to do it continue eating it, while the living parasite inside controls their minds as it eats them from the inside until it reproduces and the human host expires. Michael Moriarty, Andrea Marcovicci, Scott Bloom, Garrett Morris, Paul Sorvino, Danny Aiello appear.
