Cecily Harrington's fiancé is traveling in the Sudan, when she wins a big prize in a sweepstake and decides to postpone the wedding to spend a portion of the money on a European trip. During her travels, she meets Bruce Lovell, who sweeps the romance-craving Cecily off her feet, marries her, and takes her to his out-of-the-way cottage in the country. However, Lovell is not the charming gentleman he appears to be. Instead, he is a homicidal maniac of the most eerie, repulsive type, and is resolved to murder his new wife, just as he has murdered several other women before her. When a series of circumstances leads Cecily to realise the ghastly fact, she finds herself caught like a rat in a trap, unsure of how she will escape...
