Flight to Hong Kong (1956)

"TANGIER...FRISCO...TOKYO...MACAO...the camera races across the earth to film all the violence and vice of the world-wide sin syndicate!"

On an airliner bound for Hong Kong, Tony, a career crook who deals in stolen diamonds, agonizes over whether he should stick with his girlfriend or pursue Pamela, an intriguing novelist with whom he's instantly infatuated. Viewing Tony's dastardly deeds as great material for her new book, Pamela gladly encourages him to continue his criminal behavior.
