The trio Erik, Arne and Ingrid have been friends since childhood, the two boys always competing for the affection of Ingrid. At the naval academy Erik gets into a fistfight and is expelled, to instead become a captain of a trading ship. Before he leaves Ingrid and Erik are engaged in secret. Later, when Erik is believed to be lost at sea, Ingrid instead gets engaged with Arne.

The year is 1941 and Nazi Germany is at its peak. Hitler's army is storming into Russia. Sweden stands lonely and isolated while the air force is training intensely due to a coming attack. The squadron leader pushes his men at its hardest. It's a constant game with death where death unfortunately often wins.
