Caught this on the great Criterion website..
"A simple plot description does nothing to prepare prospective viewers of Wong Kar-wai’s In the Mood for Love. Yes, there’s a story: set in early 1960s Hong Kong, the film charts a long-lasting, unconsummated flirtation between two neighbors—Su Li-zhen (Maggie Cheung Man-yuk) and Chow Mo-wan (Tony Leung Chiu-wai)—married to others. But it’s a purely visual work, an evocation of romantic and sexual longing that plays out as an abstract emotional poem. “This film is not verbal,” said Wong in 2000. “Everything is expressed through the body, through the people, how they walk, how they move.”"
