I remember there was a scene in a movie of the former Soviet Union, in which a Soviet prisoner tried to

That movie is called Escape from Danger.

During World War II, the first detachment of the British bombing squadron was carrying out a bombing mission called "Yuanyang Tea". A plane was hit by German anti-aircraft weapons, and several crew members were forced to skydive to escape. They made an appointment to meet in Hamam. But they landed in different parts of the French capital, Paris, which was occupied by the Germans. The Germans launched a city search, and the bearded squadron leader Reginald was rescued by the city zoo. Two other soldiers also went into hiding with the help of the painter Auguste (Bourvil) and the conductor Stannis (Louis de Fenes). Even though the Germans launched a city-wide search, the painter, commander and mid-team leader met smoothly in the bathroom. After many twists and turns, the British soldiers finally took over. Several strangers originally formed a life-and-death alliance and played a life-and-death game with the enemy. At the same time, many warm jokes were made. They are ridiculously dangerous against the harsh Germans with their meager strength. They fought each other to escape from the jaws of death. Finally, the painter, bandleader and pilot flew to safety in Vichy, France.
