Dr. Pete Newmans (Johnny Simmons) is a successful sex therapist whose practice is almost completely devoted to helping people re-channel their sexual impulses. When Pete is hit in the nether regions during a friendly basketball game, his doctors discover a pituitary tumor that has delayed Pete’s onset of puberty for 15 years. Not only does Pete suddenly have an explanation for the various physical and mental issues that had been plaguing him, he undergoes what would normally be years of puberty in a matter of weeks. Mood swings, voice changes, acne and, of course, near uncontrollable erections greet Pete as he tries to navigate life as both a horny 15 year-old kid and a 30 year-old desperate to be a complete man and get the girl of his dreams.
