Shanghai

US Secret Agent Paul Soames (John Cusack) has just arrived in Shanghai to investigate the murder of his best friend, only to become quickly immersed in a web of conspiracy and lies that beset the city. Shadowed by a Japanese intelligence officer Tanaka (Ken Watanabe), Soames' investigation quickly centres on a charismatic local gangster, Anthony Lan-Ting and Lan-Ting's beautiful wife Anna (Gong Li). Before long, Soames and Anna are involved in an affair that will put everything they have at stake. As national loyalties are traded fast and loose for those of the heart, Soames and Anna must race to solve the mystery and make it out of occupied China before the city's collapse.
