After Mary tells her boyfriend she's pregnant, he enrolls in the Army and skips town, leaving her to fend for herself. With her friends Angie and Laura by her side, Mary steals a car, fakes a kidnapping and heads down to San Diego to chase her errant beau. It's a bumpy ride, however, as the girls are pursued by corrupt cops and homicidal hillbillies, not to mention their own flabbergasted parents.
