17-year-old Rodney Baverstock wins 758,000 pounds and 27 pence thanks to aunt's coupon.
Resultant riches lead to red Ferrari, a tiger, a giant mansion and bankrolling soul singer mate Sami Tate's recording career, plus crowd of hangers-on included Swedish chauffeur (and naturist) Claudia, Rastafarian gardner Leroy, long-suffering (aren't they always?) girlfriend Liz and best mate Thornton (who thought he was a robot).
