For her seventh film as a director, Xu Jinglei left her comfort zone of romantic comedies and relationship dramas to tackle a ticking clock thriller in which Bai Baihe plays Lin Wei, a detective whose five-year-old daughter Dian Dian has been kidnapped, and who receives a mysterious phone calls from the kidnapper (Stanley Huang), who is about to tell her where her daughter is, when his car is hit by a truck. His name is Yang Nian, and when he wakes up in a hospital room, he has no memory of his past. After being attacked by a mysterious assassin who murdered the two cops standing guard in front of his room, the obviously highly-trained Yang escapes, with Lin Wei in hot pursuit. Now while he tries to piece back together his past, the amnesiac must escape not only the police, but also assassins sent by a mobster he seems to have been close to in his past, as well as Lin Wei, who though suspended from the case, has decided to keep looking for her daughter. Soon, she must reluctantly team up with Yang.
