The mission is compromised when he and his fellow soldiers accidentally make contact with a civilian, rather than a Resistance member, who betrays them to the Nazis.

The film was directed by Arne Skouen and is based on the book We Die Alone (1955) by British author David Howarth.

Soaking wet and missing one shoe, he escapes up a ravine, and shoots and kills a Gestapo officer.

Baalsrud evades capture for roughly two months, during which time he suffers from frostbite and snow blindness.

The fellow Norwegians manage to move Baalsrud close to the Swedish border, but are forced to leave him in a snow cave for roughly two weeks.
