For millionaire jockey Alan York, winning is a bonus. For Joe Nantwich, victory means no cushy backhanders; and for Bill Davidson, front running on strongly fancied Admiral, triumph is an imposter. It means murder - his own.
Turning private detective, York uses Joe's underworld connections to go on the trail of the killers - only to draw a series of blanks. But when ambushed by a gang of vicious thugs, he picks up some clues, along with cuts and bruises. Bill's murder begins to make more sense. Until York finds himself in hospital, without a memory.
