A priori
After graduating top of the police academy, Iris, 27, joins a police station in the south of France. Upon arriving in this brigade composed of colorful police officers, she receives a more than mixed reception. Her in-depth knowledge of law and her insistence on respecting the rules do not please everyone, especially Victor, 54, her designated partner, a lone cop whose methods are considered outdated.
Despite their age and background differences, when Iris and Victor are assigned a case that is almost closed in advance, by combining their talents, they will discover that it is not a simple car accident but a premeditated crime. If success brings the duo closer, Victor will quickly discover that Iris is not just anyone's daughter... What secret from the past threatens to resurface?
