Heart problems force Boston cop Pally LaMarr to retire; he's in a funk and his wife Charlotte sends him packing. At Charlotte's insistence, Pally's half-brother Ray pays Pally a visit and suggests he buy a race horse to cheer up. Ray's always playing the angles, and he's got his eye on a horse that's cheap because it's been misdiagnosed. Ray knows the horse is a champion. Before they can win some money, a local mob boss, Frank Finnigan, sees the horse and steals it as payment for the gambling debt of Tony, a local jockey and single parent. Can Pally and Ray get the horse back, get Tony out of hock, and win some moola? What about Charlotte: can Pally let his heart take the lead?
