Lai (Leung) and Ho (Cheung) are gay lovers who travel to Argentina from Hong Kong in an effort to salvage their relationship. While visiting the Iguaçu Falls, however, they have a falling-out and set out on their separate ways. Lai goes to work as a doorman at a Buenos Aires tango bar, trying to earn enough money to pay for his airfare back to Hong Kong, while Ho turns to a life of partying and pimping. With the aid of his brilliant cinematographer, Christopher Doyle, Wong Kar-wai fashions an unusual urban melodrama that explores the frustrations of cultural displacement and identity in a newly globalized, post-colonial world.
