Taking its title from a racing term that signifies odds of 33/1, Double Carpet is an intense and humourous film about obsession and the strains that it puts on a relationship. Ray is a passionate gambler who lives with his long-suffering partner, Helen. At the end of a race meeting, Ray helps an old man push his car out of the mud. In return, the old man, seemingly replete with insider knowledge, gives Ray a tip on a sure thing. Ray sets about raising the stakes. He sells his car, borrows money from the bank and asks Helen for a loan. For her, this proves the final straw and she leaves. Ray's fate comes down to one race. Against the odds the horse must win.
