Harry is a rich dentist who often brings women up to his rural lakehouse. One weekend, he invites Diane, a former fashion model. On their way to the house, Diane runs a gang of thugs off the road. Humiliated, the thugs track down the couple for revenge.
A break-in and sabotage attempt occurs at a top secret research institute and the culprit is cornered and captured. The problem is that he's been badly injured and claims to have lost his memory entirely. A cat-and-mouse game ensues between investigator Tuxan, the mystery intruder Welles and the people who sent him on the mission.
