Heartbeat Detector is an immersive corporate thriller in which Mathieu Amalric (The Diving Bell And The Butterfly) plays Simon Kessler, an in-house corporate psychologist, who is asked to investigate the erratic behaviour of the company CEO (Michael Lonsdale). His investigations take him under the skin of his company, and its neutral corporate language, to dark, Cach-style transgressions.

Hailed by critics as a remarkable, ambitious and visionary film, it features an astonishing performance from Mathieu Amalric in the lead role, as a damaged yuppie and vulnerable gumshoe, who begins to unravel as company intrigues whittle away his self-belief.
