After being fired from the Forensic Medicine Center, Lu Chen made a living as a driver. At two o'clock in the morning, a soaked female passenger left an old tape recorder, which played his call to the police asking for help three days later.
She said the explosion would occur before he received his next order.
In order to survive and to find his father who had been missing for ten years, Lu investigated the covered-up "Salt Spray Warehouse Case". But he soon discovered: every recording was a death script written by the murderer in advance.
