This complicated murder mystery is set aboard a fog-bound ocean liner. Eccentric millionaire Alonzo Holt (Robert McQuarrie) is the first victim, knocked off for his vast fortune. Two more murders occur before phony medium Madame Alva (Helen Freeman) offers to help solve the mystery. Alas, the guilty party is very close to Madame Alva, and doesn't intend to have her spill the beans. Once the killer has been revealed, the explanation as to how the three murders were committed defies logic, but since when has that ever stopped Hollywood from churning out "locked room" puzzlers of this nature? Leading lady Mary Brian ends up with one of the few "nice" characters as her boyfriend in the closing scene.
