A movie mogul down on his luck hopes that sex really does sell in this irreverent comedy for adults only. Uranus Studios have built their reputation around respectable and critically acclaimed films suitable for family viewing, but in the late '70s, that's the last thing anyone wants to see, and the studio is on the verge of going out of business. P.G. Dartmouth (David Kelly), Uranus' top producer, is desperate for a hit when his wife, Henrietta (Candy Samples), manages to land the studio a contract to make a film about a space mission launched jointly by American and Soviet astronauts, primarily through her extramarital adventures with famous diplomat Hans Pissinger. While the million-dollar budget for the space epic will help keep the wolf from the door for a while, it's not enough to put Uranus securely in the black until Dartmouth gets an idea -- use part of the million bucks to produce a sleazy sex film guaranteed to turn a profit. But can Dartmouth make his underwater porn epic "Deep Jaws" (featuring sexually insatiable mermaids) without tipping off his unknowing financiers -- especially while including a role for his nerdy son, Junior (Richard Nathan)? Deep Jaws also features Sandy Carey, George "Buck" Flower, and Gordon Herigstadt.
