Separated for years, iconic Chinese painting Dwelling in the Fushan Mountains is about to be united again in a grand ceremony. Before the ceremony could take place, a British arms dealer steals one half of the painting from a Taiwan museum. Customs agent Xiao Jinhan (Andy Lau) is immediately called in to retrieve the stolen painting just as Japanese smuggler Yamamoto (Tong Dawei) aims to steal the other half from a Zhejiang museum. The half in Zhejiang is protected by Jinhan's insurance investigator wife Yuyan (Zhang Jingchu), who doesn't know her husband's real occupation. With the mysterious Lisa (Lin Chi Ling) playing both sides, who will come out on top and put the painting back together again?
