The story of Romek Cudakowski, a musician who, risking his life, freed from the ghetto his biggest competitor, an exceptional violinist Szymon Akerman. The men had conflicted before the war broke out because Romek thought that Akerman would take away from him the most lucrative odd jobs. After escaping from the ghetto, Szymon plays in the Romek's orchestra in the brothel, whose usual guests are Germans. The better the men get to know each other, the more the differences that once divided them fade away.

The film belongs to a series of feature films titled Whoever Saves One Life, Saves the World Entire, presenting stories of Poles rescuing their Jewish neighbours, friends and complete strangers during WWII.
