Bina returns to an anxious Aleksander, who immediately perks up when he learns who Motyl really is. He agrees with Stach that Bina is more valuable alive and begins to plan all the other supplies that she can smuggle into the ghetto.

However, Bina asserts that she wants to fight, letting her true feelings for Aleksander show. Aleksander reveals that he feels the same way but admits that memories of Karina and Jakub make him feel guilty. The two agree to sleep together just once. After they do, an ecstatic Bina resolves to write about this experience so that she will never forget a moment of it.

Aleksander leaves, and Stach and the Żegota help Bina set up a covert assembly line through the sewers, delivering weapons and ammunition to Zelda. Twelve days later, a distraught Eryk arrives at the apartment: Almost 100 young girls are being held hostage at the Great Synagogue for four days before they will be transported elsewhere as victims of sex trafficking; Dina is one of them. Zelda has instructions regarding this for Bina, but Eryk begs Bina not to carry them out, as he wants his sister to live.

Eryk hands over his father’s prized violin, a Stradivarius, and implores Bina to trade it for Dina’s life.
