When Paul makes a satirical toast behind the Iron Curtain, racing-car driver Janos Takacs (Eric Braeden) courteously joins in and finds himself in prison. Paul tries to make up for his frivolous action by freeing him with the help of his sister Marika Takacs (Gia Scala) and former prisoner Istvan Zabor (Telly Savalas).

A love triangle is revealed when Paul grabs the opportunity to make a world speed record for Greek magnate Alex Staphos (Rossano Brazzi), causing both men to disclose intimate secrets.

Pete Gaffney (Jeremy Slate) and Paul form a racing partnership with Clive Darrell (Edward Mulhare), but his wife Rhona (Sally Ann Howes) is sabotaging the car.
