The Danish resistance movement stepped up its activities towards the end of the war. One night, an English agent arrives by plane, is injured and is taken in by local resistance fighters. The agent and the resistance fighters plan actions against the Germans, but there must be a traitor among them, because the Germans are always very close by.
