Alien Trespass

A spaceship crash in 1957 California leads to the escape of the Ghota, a murderous monster bent on destroying all life forms. In order to capture the Ghota, a benevolent alien named Urp takes over the body of an astronomer (Eric McCormack) and enlists the aid of a waitress named Tammy (Jenni Baird). But, unless Urp and Tammy are successful, mankind is doomed.
