IMDB

Audrey Hepburn and Albert Finney play a married couple about to set off on a trip. This triggers a montage of all of their trips, which is a microcosm of their marriage, which lasts the entire movie. You see them meet, fall in love, argue, make up, cheat, etc.
This movie is a masterpiece. The transitions between their trips are great, the acting is great and the characters are well-developed and both likable and unlikable at the same time.

10/10
