Repressed Accountant Kees Popinga (Claude Rains) becomes completely unglued when he discovers that his company's funds (along with his own life savings) are being embezzled by the Company President (Herbert Lom). In a fit of raging indignation he accidentally kills the embezzling president. He then flees to Paris with a large sum of the remaining company funds.

Can a sympathetic Parisian Detective (Marius Goring) catch up to Popinga before his self-destructive path ends in suicidal violence?
