We open up with George Hartford callously dumping (and dumping on) his former fiancee. He's an owner of a southern California auto dealership, doesn't think much of old fashioned values like marriage and fidelity...he's a swinger who says if it feels natural to you, it's right, and all sorts of similar platitudes. Both the woman George is dumping and his psychiatrist about-to-be-married brother warn him separately that his lifestyle and (lack of) values are going to catch up with him, and that someday he's going to run into a "buzzsaw" because of it.

That "buzzsaw" is in the form of Laura Prentiss, whom he meets at a resort on the pacific coast. She's beautiful, mysterious and strangely alternates between being seductive and remorseful. She also has a vintage Mercedes in "british racing green"...George can't decide whether he's more captivated by her or the car. The car is a gift from her rich husband, who's also a parapsychologist who's into some heavy, er, doo doo...clairvoyance, mental telepathy, ESP. She seems nervous thinking about him, but gives into her (and George's) lustful intentions.

Later, when George returns to his own (locked) cabin, he finds a mysterious, small man who identifies himself as Mr. Prentiss, and warns George to stay away from his wife.

George obliges, and is somewhat uneasy. Returning to his auto dealership in Los Angeles, one week later who should stop by but Laura Prentiss. And who should foolishly decide to join her for another fling but George.

And while they're driving off, who should happen to ring chimes in their heads and say "Now you'll both suffer the consequences" but the voice of Mr. Prentiss, even though he's overseas in India meditating....
