Cecily Harrington, engaged to Nigel Lawrence who is shortly returning from the Sudan to marry her, wins a big prize in a sweepstake and decides to postpone the wedding and spend a portion of the money on a European trip. She meets Bruce Lovell, a much-traveled he-man, who sweeps the romance craving Cecily off her feet, marries her and takes her to their out-of-the-way cottage in the country. But Lovell is a homicidal maniac of the most eerie, repulsive type, and is resolved on her murder, just as he has murdered several other women before her. When Cecily realizes the ghastly fact she finds that she is caught like a rat in a trap.
