Malaysia Airlines Flight 370 disappeared in March 2014 with 239 people aboard, and the official four-year investigation closed without a confirmed cause. This film brings in independent aviation experts and investigators to go back through the satellite handshake data and ADS-B records that tracked the Boeing 777's last known movements, checking the original report for gaps and contradictions. New analysis points to a manual shutdown of the plane's transponder, cutting off its signal deliberately rather than through malfunction, and reopens scrutiny of flight simulator sessions found on the captain's home computer that mirrored parts of the missing plane's path. Interviews and reconstructed flight data walk through competing scenarios, from mechanical failure to a deliberate act by someone in the cockpit. The film does not claim to solve the case; instead it lays out what the evidence supports and what it still cannot answer, leaving the question of accident or crime scene open at the end.
