Staff at Heathrow prepare for the arrival of Air Force 1, and although the airport is quieter than usual, it is still a huge effort logistically to make sure things run smoothly. Meanwhile, security officer Estafania scrutinises the contents of passengers' hand luggage, as well as their face masks, and airside officer Ian has his hands full.

Passenger experience manager Numan is back after a year on furlough and faced with a terminal of 24 passengers who are missing 50 pieces of luggage - and it's his job to find them. Out on the airfield, Inspector Shard and Sergeant Dawson receive word of a man who is wandering around on the apron, sparking a cross-terminal manhunt.
