The women from the hood come together to stop Mr. Marionnaud from destroying their homes. Simultaneously, Ezéchiel trains Rosa and the women on how to use guns effectively.

As the night of the heist approaches, Rosa and her friends are determined to steal the drugs. On election evening, the police are waiting at the dockyard for the thieves to execute the robbery. The drugs are loaded onto the van while the thieves pick up the van in an ambulance, according to Ezéchiel’s plan. However, there is a crossfire between Marionnaud’s men and the women.
Chloe is shot, but the women manage to put her in the van and exit the dockyard. To everyone’s surprise, Chloe wakes up and reveals that she was wearing a bulletproof vest the entire time. The van full of drugs allegedly leaves the docks and enters the city. Malik and the cops stop the van, only to discover a group of local women inside. The women claim that they are transporting the stolen money for Ezéchiel.
A flashback reveals Rosa and the group planning their escape from the dock. After successfully taking the van full of drugs, Kim drives the van inside a carrier vehicle. An identical van is set free in the city that the police assume to be the stolen van.
The cops find the money stolen from Castel Bank inside the van while the women blame Ezéchiel for stealing it. With the cops off their tail, Rosa and the women take the drug van away to burn the drugs. They also burn their fake beards and costumes, putting an end to their heist.
The results for the election are announced, and Mr. Marionnaud is re-elected as mayor. He celebrates with Chloe by his side, wearing a T-shirt with his pet chicken’s photo on it. Laurent arrests Mr. Marionnaud for ordering the heist. He claims that the T-shirts were paid for in cash by Chloe, and that cash was stolen from Castel Bank. Chloe says that Mr. Marionnaud asked her to make the T-shirts but gets angry and slaps her before Chloe slaps him back.
Malik is then informed about the attack on Chloe and shows up to see her.
What transpires for Alex? Alex reveals a dire situation - she's been shot. In a panic, the girls rush her to the hospital, only to be halted by police barricades that prevent them from leaving town. Kim takes matters into her own hands, driving Alex behind Rosa and Sofia's car. However, her alter ego compels her to speed through the checkpoint, alerting the cops to Kim's car.
Malik attempts to rush back to the checkpoint, but Chloe, determined to be by his side, handcuffs herself to him and forces him to take her along. The cops give chase as Alex's condition deteriorates, with blood loss becoming increasingly severe.
Chloe, in an effort to distract Malik, swerves his car, causing it to topple and crash, effectively blocking the path for the other cop cars pursuing Kim, Rosa, and Sofia. Kim takes off while Laurent continues the chase.
How does 'Cash Queens' conclude? Rosa makes a heartfelt request to Sofia to take care of her children and stops driving. She surrenders to the cops, who still possess her DNA, while Kim and Sofia race to get Alex to the hospital.
Chloe and Malik are left unconscious in his car after the crash, and the episode ends with Laurent arresting Rosa from within her vehicle.
