Problems with his rocket compel space-traveling vigilante Shep Ramsey (Hulk Hogan) to spend some time on Earth. Plunking himself down in the middle of suburbia, he rents a room from Charlie (Christopher Lloyd) and Jenny Wilcox (Shelley Duvall). Shep attempts to acclimate himself -- he skateboards, he accosts a mail carrier -- but he's destined to be a fish out of water. But when his outer space enemies arrive and pick a fight with his new friends, Shep is ready to prove his mettle.
