Agrochemical giant Saskia is preparing to launch its latest product, but MP Guillaume Delpierre is suspicious after visiting the bedside of his childhood friend, Michel Villeneuve, a farmer with an aggressive cancer.
The body of a Saskia employee is found in the Seine, and the company works to convince the family that it was a suicide. Villeneuve is anxious to file a complaint with Delpierre, but his family would prefer he accept Saskia's compensation.
Delpierre and his assistant Romain want to demonstrate the dangerous nature of the pesticides they wish to ban. They present a scientific study on Lymitrol, Saksia's flagship product, whose results are unequivocal.
Though working with Bowman, a lobbyist for Saskia, to discredit the Lymitrol findings, disgraced journalist Claire finds herself compelled by Chloe's findings.
Delpierre and Villeneuve are preparing to defend the anti-Lymitrol amendment when Bowman decides to leak a tenuous link between Delpierre's wife and the Paoletti Foundation.
Delpierre and Villeneuve both face challenges--one in the Assembly, the other in court opposite Saskia. Meanwhile, Chloe and Claire meet with varying success.
Saskia will stop at nothing to kill Delpierre's bill, including possibly relocating Vallopak--a company providing hundreds of jobs in his constituency--or digging into Romain's troubled past.
So that his past can't be used against Delpierre, Romain resigns. Meanwhile, Bowman forces Claire to sign a termination contract and confidentiality agreement. Will Delpierre be able to achieve his goal?
