Réussir ou mourir

While Delphine leaves for a business trip, leaving Matthieu and Emma alone, the commandant receives notice of the murder of Maryline Hardouin, 22, a waitress and actress, in an 18th century castle, during the filming of a series, in which she participated two months before with a small role. After claiming the check for her performance, she was hit on the head, and bled to death on a bed as the killer watched her death. According to the producer of the series, she was very ambitious, but not able to withstand the pressure of filming. A train ticket to Montpellier in her pocket indicates that she wanted to get away from her current life. During the investigation, Matthieu gets a call from the hospital because Emma needs an emergency operation.
