A 40-year veteran cop stables his horse (illegally) in the NYPD stables where he is a groom; he is shot trying (unsuccessfully) to prevent her being stolen. The thief knows that the filly is expecting, that the sire is a champion racehorse. The plan is to sell her foal to the highest bidder. The incompetent thief is in over his head with a gangster literally calling the shots. The chase scenes are reminiscent of a Keystone-Cops-type western.
