During an endurance race organized by the company where he works as an intern, 24-year-old Antoine Perrin suffers a sudden epileptic seizure and dies. The coroner confirms death was caused by a stimulant. Marquand and Alice are suspicious of all interns, who are struggling to get the only permanent position in the company; the race being a part of the trials they are put through, along with the endless working hours, the sleepless nights, and the pills to put up with it. Alice is also increasingly turning to morphine to withstand the aftermath of her surgery.
