Black Box

Mathieu, a skilled black box analyst, is assigned to investigate the cause of a fatal crash involving a new aircraft. Although the official investigation concludes with a clear explanation, Mathieu feels uneasy about the evidence presented. Upon reviewing the flight recordings again, he notices unsettling inconsistencies that suggest the tape might have been tampered with. Ignoring his supervisor's instructions, Mathieu starts an independent investigation, driven by a strong desire to uncover the truth. This unauthorized inquiry soon puts not only his job but also his personal safety at risk.
