While on vacation in Mexico, a wealthy woman dies in the back seat of the car owned by her daughter Janet (Mary Scott) and son-in-law Evan (George Peppard). Reporting the woman's demise, the couple returns to find that the car has been stolen -- and with no corpse, they will be unable to claim Janet's inheritance. In desperation, Janet and Evan hire a sleazy private eye named Tomas Salgado (a role made to order for Peter Lorre), who agrees to locate the body and ship it back to Los Angeles...but only for a hefty price.
