A young woman dies by suicide and leaves all her belongings to her next-door neighbour, who becomes determined to investigate her reasons for taking her life.
Sture Letterström and Kurre Svensson take on the task of rescuing a secret document during World War II from a group of Swedish Nazis. Since both of them are known by the local Nazis, Sture takes on the role of Miss Märta Letterström, and Kurre also has to make use of his feminine side as well as a dress.
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.
