A speed-boat racer suffers amnesia after an boating accident and goes to his isolated villa to recuperate. His relationship with his wife is troubled, so he starts an affair (sort of) with the another woman, which results in one of the three of them being shot. But there are several more twists--and more murders--to come.

Trivia, insights & behind the scenes
Tonino Ricci directed this under a tight budget, reusing the same villa location for multiple gialli that year.
A minor entry in the 1971 giallo boom, when every Italian filmmaker raced to out-Argento each other with amnesia plots and coastal settings.
