'Bill (Syd Brisbane) and John (David Field) don't have much going for them, a crumpled couple of friends on the slow side of up. They like their dog races and when the infamous Alex Silver offers them a chance to not only race a greyhound for him, but actually own it on paper, the men jump at it - albeit with some reservations from Bill. The dog, named Silent Partner, offers them a chance to do something in their lives, and when it comes a close second at a bush track, Bill and John sense they are onto something here. But the next race, in the big smoke at Wentworth park, doesn't go so well, and the instructions from Silver are severe: dope the dog.' (Source: Urban Cinefile website)
