David Galaxy is a playboy astrologer and effortlessly charming bachelor who beds beautiful women as easily as he reads their fortunes.

His job affords him a healthy income and the freedom to do what - and who - he wants: he's engaged in an affair with a female MP, has a number of young blonde girlfriends, and has other business interests including a beauty pageant (with perks, naturally).

Spending much of his time gambling, drinking, and arranging dubious set-ups with his best friend Steve, he's aghast to find a Chief Inspector from the Metropolitan Police at his penthouse flat door one afternoon, enquiring as to his whereabouts some five years previously. A cold case has been reopened and implicated David in a crime that saw someone murdered, but as long as he has an alibi...

Meanwhile, Steve has concocted his own plot for his friend: he's set David up with Millie, a girl about town notorious for never having had an orgasm, and arranged an underground gambling syndicate on the basis of his astrologer friend being able to end her drought!
