Several women enter a science fiction author's life over the course of a few years, after the author has lost the woman he considers his one true love.

In the aftermath of In the Mood for Love (2000), after losing Su Li-zhen, the love of his life, the journalist and author, Chow Mo-wan, returns to Hong Kong to write a book. Obsessed with finishing his new science fiction novel, Chow begins a series of romantic relationships with four different women; however, the more he tries to understand and forget, the more he finds himself haunted by his past. In his novel, a train sets off for a remote, mysterious destination in 2046, where passengers hope to reclaim their lost memories. Now, a maelstrom of beautiful and sad feelings, secret longings, and wild passions govern Chow's life, who's been trying to relive a life-altering experience ever since his doomed affair with Su: an emotionally intense relationship that has defined Chow's life and condemned his future romances.

The story evolves around the main character, Zhou Mo Wan who writes a novel about a mysterious train that leaves for a place called 2046 every once in a while. Everyone who boards that train has the same intention - which is to recapture their lost memories. It is said that in 2046, nothing ever changed. Nobody knows for sure if it was true, because nobody who went there had ever come back- except for one. He had been there but he chose to leave. He wanted to change.—chicken noodles
