Infiltré(e)

After the death of his son's babysitter, caused by UBH, a synthetic drug that is starting to flood the market, Commissioner Max Vernet convinces his superiors to set up an infiltration, the only way to trace a production and distribution network that is as mysterious as it is dangerous. To do this, he meets Aurélie, a single mother and chemist in the police, and asks her to offer her services as a chemist to the network run from Marseille by the charismatic Jesus on the pretext of being able to improve the product. But Aurélie refuses, her family balance and her son, whom she has been raising alone since the death of her partner fifteen years earlier, matter more than anything.

Aurélie has discovered that her son Jérôme owes 50,000 euros to a dealer and has no way of settling this debt. She decides to embezzle a stock of UBH that she was supposed to destroy, but is unmasked by the IGPN. Max then makes a contract with her: if Aurélie accepts the infiltration mission, justice is ready to forgive the crime and Max will take care of settling Jérémie's problem with his dealer. Aurélie has no choice but to accept and soon finds herself in contact with Richard Le Moal, a UBH dealer who was identified by Max and his team.

When Le Moal discovers that Aurélie is in contact with the police, he tries to escape but is knocked down by a car. As he lies dying in his hospital bed, Le Moal agrees to give the phone number of the head of the UBH network. Aurélie contacts Jesus and Nikita as they have just started a turf war in Marseille with a gang of Albanians. Aurélie offers not only to replace Le Moal but also to improve the UBH thanks to her talents as a chemist…
