Top chef and self-confessed petrol head James Martin tells a tale of triumph and tragedy as he joins Sir Jackie Stewart on an incredible journey though the legend's life. James get's a taste of the swinging seventies, and an insight into Jackie's jet set lifestyle as the pair cruise through the Alps in a Pantera supercar before Martin dons the Flying Scotsman's tartan helmet and attempts to drive a 1973 Tyrell F1 car around the iconic Monza circuit.
