Lonely spinster Martha (June Lockhart) and taciturn coffin maker Luke (John Anderson) meet each other via a mail-order lonely hearts club. Agreeing to wed Luke sight unseen, Martha subsequently discovers that she is her new husband's second wife; it seems that wife number one died under very mysterious circumstances. Thus, when Luke begins spending an inordinate amount of time puttering in his cellar, Martha's suspicions are aroused -- and before long suspicion gives way to terror...and desperation.
