 The Gizmos team is called in when a passenger jet is temporarily hijacked by remote control, and a ransom demand is sent to an airport by someone calling themselves  Icarus . Whilst Beckett clashes with the airport s bureaucratic head of security, Ros investigates the state-of-the-art navigation system on board the empty jet. But then the doors lock, and the jet takes off with Ros still trapped aboard. Ed and Beckett must race against the clock to discover the identity of  Icarus  before the jet runs out of fuel.
