The job proves nerve-wracking, and soon Chuck finds himself pledged to help Eddie's lovely, fearful, prisoner-wife Lorna (Michèle Morgan) to escape. The result leaves Chuck caught like a rat in a trap, vainly seeking a way out through dark streets. But the real chase begins when the strange plot virtually starts all over again...
