Suburban dwork, family man and wife swapping swinger Stan Putterman (Gerrit Graham) installs a new satellite dish and bumbles the task. As a result the dish picks up a transmission that causes a slimy alien, with several rotating eyes, to emerge from the tv set. The three feet by five creature is a mutated household pet from the planet Pluton. It eats everything it can grab and when it outgrows its size, it starts dining on the Puttermans. The family includes the swinging mom (Mary Woronov), the young wide-eyed neurotic boy (Chad Allen), the Cyndi Lauper lookalike teen sister (Diane Franklin) and, gramps (Bert Remsen), the crazed armed-to-his-teeth survivalist nut, who dines on lizards’ tail jerky.
