Passenger 1 (Spyfall)

On an aeroplane above the Pacific Ocean, a human spy delivered a package, in the form of a washbag, to another undercover operative. He claimed he had found it in the aisle, where he believed she had forgotten her bag. The second operative replied that she was clumsy, and took the package from him. He wished her an enjoyable flight. (TV: Spyfall)
