[5] Ruthless criminal Zhang Hua (Wang Qianyuan) and his gang impersonate as police officers to abduct wealthy businessmen.

Setting a trap outside a Beijing karaoke club, they hit the jackpot with Hong Kong film star Mr Wu (Andy Lau), forcing him into their car on the pretext of being investigated for a hit-and-run.

Then Wu is made to witness the execution of Xiao Dou (Cai Lu), Zhang's last abducted victim, who failed to have his ransom paid within 24 hours.

As 9pm approaches, the police stage a final desperate rescue attempt based on an unreliable tip as the kidnapping gang, fearing they'll be Zhang's next victims, decides to kill the hostages before the deadline.

Production of Saving Mr. Wu was kept at a low profile and was first revealed when actor Liu Ye wrote in his Sina Weibo account that he was working on a film with Andy Lau.
