The rituals of courtship, romantic rivalry, and love play out three times as a man vies with a villain for the girl. In the Stone Age, the rivalry is set off by dinosaurs, a turtle used as a ouija board, and a round of golf with stones. In ancient Rome, the men display their brawn through a chariot race, using dogs instead of horses. In contemporary times, the man finds himself overcome by modernity, including a very fragile car.
