During World War 2 when some Swiss inspectors inspect one of the camps, one of the Germans accompanying them sees that the inmates play football(soccer). And when he recognizes one of the men, Colby as a former player for England, he suggests that his men play against a team of Germans. Colby agrees provided that his players be provided with certain amenities. At the same time, one of the prisoners an American, Hatch is planning to escape. But his plan hits a snag because of the football game. He joins the team cause it's the only way his plan can work. The officers at the camp want him to go to Paris, where the game will be held, so that he can contact the underground and see if its possible for the team to escape. Hatch makes it and after meeting them, they think there's a way but Hatch has to get caught so that he could be sent back to the camp so that he can inform the team of the plan. Which he does but unfortunately the Germans are keeping him in isolation so Colby must convince the Germans that he needs him for the team so that he could be released.
