Nick and Nora Charles are looking forward to a day of leisure, but when they make a trip to the race track, they learn that a jockey, who was recently accused of throwing a race, has just been found shot to death. With his friend Lieutenant Abrams in charge of the case, Nick has difficulty keeping from getting involved. Then a special state deputy, in charge of investigating gambling scandals, comes to see Nick. He tells Nick that the jockey could have been silenced by a gambling syndicate, and he asks for Nick's help. Soon Nick is fully involved in a complicated and hazardous investigation.—Snow Leopard
