On March 8, 2014, Malaysia Airlines Flight 370 disappeared from radar screens and seemingly vanished off the face of the Earth, while flying from Kuala Lumpur International Airport, Malaysia, to its destination, Beijing Capital International Airport in China. Many theories have since been proffered about its fate and that of the 239 people on board, but nothing concrete has emerged. This documentary charts the search for the aircraft, from teams using hi-tech hydrophones to listen for the black box recorders, to cutting-edge submersibles mapping the ocean floor for clues.
