Ten years after the death of millionaire Cyrus Norman, his will is to be read out to his six relatives, including Joyce Norman (Paulette Goddard) and Wally Campbell (Bob Hope). Organized by Norman's lawyer, Crosby (George Zucco), the six meet at Norman's eerie New Orleans Gothic mansion. During the reading, the superstitious housekeeper declares that someone will be dead by midnight. Wally fears for Joyce when she is declared the sole inheritor, but all are alarmed when Crosby turns up dead.
