As a cinema actor, Lloyd Bridges never really gained major star status, but his television appearances, especially in the long-running TV series Sea Hunt, made his face familiar to millions. He is a useful presence in this generally uninvolving Second World War action adventure. The film was shot in England, and a supporting cast of British TV names such as Mark Eden and Andrew Keir does what is expected of it, but the overall style is curiously flat considering the director is Paul Wendkos, established since the mid-1950s yet obviously slumming with this material.

The film depicts an account of Allied Combined Operations Headquarters commandos executing a daring raid on the German-occupied French coast during the Second World War. The story is based on the commando raid on the French port of St. Nazaire.
