Hongkong Honeymoon (1960)

A man, told that he only has a few months to live, gathers all the money he's saved for the past ten years and takes a plane trip to Hong Kong for one last fling. He strikes up a friendship with a stewardess on the plane, and they hang out together when the plane lands in Hong Kong. They wind up getting married and travel to Macao, where they get mixed up with a missing role of microfilm and foreign spies.
