During the latter part of WW2, The Danish resistance is taking care of an English agent after getting hurt on his arrival by plane. The agent's goal is a sabotage action, but a traitor is among them.

It is the last winter of World War II. The Danish resistance movement has intensified the fight against the occupation troops. But the Germans respond brutally again. On a dark winter night, an English bomber is heading over the country. On board is an agent who must be parachuted. Bad weather forces the agent to jump far from the planned location and he lands in a small village. Here, local resistance fighters hide him. One of the leaders of the resistance movement arrives from Copenhagen and sabotage actions are planned together with the agent. But the Germans are right on their heels...closer and closer...there must be a traitor among them.—Nordiskfilm
