A Sephardic Jew, she applies at the local Jewish center to migrate to Israel when the rabbi informs her about her daughter, Raşel, who was taken away from her as an infant and has been jailed for breaking into the Club Istanbul, a nightclub managed by Çelebi, prompting her to forego her departure.

At the prison, Matilda runs into Çelebi, who demands that she work for him in the club, located in the Pera district, in exchange for Raşel‘s freedom and a place to stay.

Matilda realizes that she had met Çelebi before her imprisonment, and after confronting him, he reveals that he was Aziz, a servant who tried to warn the Aseos about Mümtaz's betrayal, only to be framed for theft and fired.

Raşel strikes up a relationship with an ethnic Turkish taxi driver named "Fıstık" İsmet, the estranged son of local gangster Ali Şeker, and is impregnated by him.

Kürşat, with the help of Ali and his thugs instigate the Istanbul riots, destroying non-Turkish-owned stores along the Grand Avenue of Pera and attacking minorities they find.

After Rana tells Çelebi that Raşel has been stealing again, he contacts Ali Şeker, now a slumlord, to convince Ismet to return to Istanbul, offering him a job as a bartender at the club.

At the Club, Selim is framed and arrested for drugs charges by Keriman, an ambitious dancer who is also the lover of Fikret Kayalı, an unscrupulous developer who has been buying up properties vacated by non-Turks following the riots.

While playing backstage, Rana finds a diamond near the cage's levers, which Raşel recognizes was detached from Keriman's outfit which she wore on the night Selim was killed.

As the staff move out of the premises, Keriman arrives to pick up her things, but is confronted in her room by Raşel, who learns from Rana that she had flirted with İsmet.
