Led by Captain Jubran, Ihe Internal Security Force goes undercover to catch fugitive drug-dealer Al Deeb when they receive information about his whereabouts.
When the Internal Security Force gets into a firefight and Jubran gets shot, Al Deeb’s half-brother Yazan is accused of shooting him. Safi helps Yazan hide.
Safi decides to send Yazan to Cyprus with a fake passport while Sama prepares to take on her late brother’s mission and goes to the neighbourhood undercover.
After being beaten up by her brother, Sama is taken in by a sympathetic Safi’s mother despite Safi’s disapproval. One of the basement women decides to escape.
Duha is beside herself with rage when she finds out Sultan is behind Safi’s arrestment. Sama contemplates Sultan’s condition to drop the charges against Safi.
When Al Hoot leaves unnoticed, the Force suspects there is a passageway linking the grocer shop to the adjacent neighbourhood. Safi comes clean with Warda.
Sama tries by all means possible to get a job at the grocer shop to find out whether there is a passageway. A suspicious Warda rummages through Sama’s stuff.
Safi takes an injured Sama to the hospital while his relationship with Al Hoot takes a hit. Meanwhile, the Force interrogate people about Sama’s disappearance.
When Sama’s health improves, she devises a plan to reach out to the Force. Meanwhile, Suad and Bulbul get arrested and are forced to cooperate with the police.
Sama’s plan succeeds as she contacts Ghassan who gives orders to break into the place. Rasmiya, Haram and Warda arrive to a shocking surprise at the chalet.
