This sci-fi actioner stars "Rowdy" Roddy Piper (yes, the ex-pro wrestler) as Nada, a drifter desperately in need of a decent job. He lands a temp job at a construction site, but strange doings in the church across the street cause him to investigate, and after the place is raided he discovers what looks like ordinary sunglasses have special lenses to be able to see the world for what it really is. Unfortunately, the world just so happens to be inhabited by an alien race who have taken over the Earth and forced humans into submission through subliminal messages while they are slowly turning it into a place of their own. When Piper starts fighting back, he gets himself into a whole world of trouble. With no one believing him and everyone after him, it looks like it's up to one man to try to take down a world of powerful aliens singlehandedly. Keith David and Meg Foster co-star. John Carpenter writes and directs.
