Meanwhile, Zain (Anas Tayara) tries to convince his brother Musa (Tim Hassan) to back down from counterfeiting the money for fear of the consequences, but the latter refuses, arguing that there is no longer any room for retreat. At the same time, Al-Ajjan tries to take the key to the printing press from Bilqis, but he suspects her relationship with Musa and asks her if she has fallen in love with him.

Security investigations and conspiracies are revealed Events escalate when Dalal Khanum (Mona Wassef) asks Musa to bring traffic camera data to investigate a run-over incident involving three children, which she believes was planned.
