In 1940, during the occupation of France, a Nazi officer learns that one of his captives, Danny (played by Sam Gittins), is a skilled boxer. He coerces Danny into participating in boxing matches for the amusement of his troops. However, the prisoners see an opportunity in these bouts to orchestrate a daring escape plan before they are transferred to Germany, where escaping would be nearly impossible. The success of their plan and their chance at freedom hinge on how long Danny can continue to fight.
