Kirby's luck turns when he sleeps in the bed of a friend of a friend who is away for the weekend. In the middle of the night, a naked young woman gets into the bed and makes love to him in the dark, mistaking him for the bed's usual occupant. Caught in the middle of sleep, all of Kirby's sexual hang-ups disappear and he performs quite well. Discovering her mistake, the woman – named Bonnie Lee Beaumont – is at first furious but within minutes the two of them fall deeply and enduringly in love with each other and consummate their new-found love for the rest of the night.
