The Lourmel couple are taking part in the final round of a TV game show: the wife has to answer questions; if she fails, her husband drives a racing car to make up the lost minutes. Moments before the start of the show, a phone call informs Lourmel that her six-year-old son has been kidnapped, and that the ransom is the amount to be won on the game show.
