If you borrow successful concepts from movies as Body Double and Back to the Future, blend them with creative graphics, special effects, a pudgy Rene Summers and the long staff of Tom Byron, what you end up with is more like a sex oddity!
Byron gets jealous watching some guy "in and out" the girl of his dreams through binoculars from his futuristic house high in the hills of California. So, to prove his love for her, he takes her on a journal across time in his fathers time-traveling machine.
Despite his father's warnings not to touch the time traveler, Tom and Rene Summers travel to 1955 where they watch Herschel Savage "make it" with poodle-skirter Tamara Longley in a "1965" Mustang convertible.
They drift through time, always popping in on people engaged in various forms of sex. For instance, they drop in on 1965 to a love-in with some groovy outdoor action, as well as catching Sharon Mitchell in a cameo appearance as a shrink seducing her nymphomaniac client on what else . . . the couch.
