When they first met, he was an ambitious young man who talked a lot, and she was a future star who aspired to become a famous actress. But now, after marriage, they have changed. He has become a boring office worker who does not like the job in the company, and she has become a bad actress who is not popular. After a performance, husband Frank (Leonardo DiCaprio) and wife April (Kate Winslet) got angry, and the resentment between the two for many years finally broke out. Could it be that marriage can't escape the seven-year itch? The grief-stricken April sorted out photos and found a photo of Frank when he was young. Thinking of the "beautiful Paris" he once described, she proposed a plan to "move the whole family to Paris" to save the family. However, this seemingly unattainable plan became a catalyst, pushing the two into a more painful abyss of marriage.
