This week in Sète, the police are gradually getting closer to the culprit… While sexual assaults are increasing, and the latest victim is none other than Sara, a new face is in the police's sights. It's Joël Tundis, Mona's new darling. During her interrogation, Sara breaks down. Convinced that Joël is the man who attacked her, but unable to prove it, the policewoman collapses. At the hospital, she finds herself confronted with the harsh reality of her trauma. She can no longer keep her discomfort to herself, and finally confides in her wife, Roxane. At the police station, this announcement had the effect of a tsunami. Everyone is mobilizing to find a new path. A gym then attracts the attention of the police. They quickly set up an infiltration operation, led by Nordine. When consulting the customer file, a profile stands out: that of Antonin Delartain. The man makes masculinist remarks on the internet, and uses the same sports elastics as the rapist… Could he be the sexual attacker who terrorizes all the women in Sète? Time is running out. The culprit is about to do it again. Who will be the next victim? Watch “Tomorrow belongs to us”, Monday to Friday at 7:10 p.m. on TF1.
