Now and then, a new and small World War 2 film comes out of the woodwork and enters the Netflix UK Top 10.

This newly released film, currently at No 4 in the British chart, tells the amazing true story of Gunnar Sønsteby.

A member of the Norwegian resistance during the German occupation of his country, he risked his life against the Nazis.

Known as Agent No 24, the brave young man became Norway’s most decorated war hero and was the only person awarded the War Cross with three swords, the nation’s highest military honour.

During the Second World War, he was involved in numerous sabotage operations, intelligence gatherings and informant assassinations.
