A former race-car driver-turned-writer decides to expose a ruthless, womanizing Grand Prix race driver in a book. However, his scheme explodes when his life is saved by this man, who is actually sensitive and misunderstood.
While not Corman's best work, there is a good cast here with Mark Damon and uncredited voice-overs by William Shatner. The script was written by Robert Wright Campbell, who received an Academy Award nomination for his screenplay "Man of a Thousand Faces", the biography of Lon Chaney. Robert's brother William also stars in this alongside Damon. (William, interestingly, filmed "Dementia 13" immediately after this, under the guidance of Corman protégé Francis Ford Coppola, and also had some "Star Trek" appearances -- with Shatner!) William Campbell's ex-wife, Judith Exner, was notorious for having affairs with President Kennedy and two Chicago mobsters... but that is neither here nor there.
