Desperate for some experience to bolster his next application, Qin contacts his cop cousin Tang Ren (Wang Baoqiang) who lives in Bangkok. Tang isn't the picture of professionalism Qin was hoping for, however, as it transpires he is a drug-addicted rogue at the very bottom of the local police hierarchy. When Tang's fingerprints are found at the scene of a murder he and Qin must go on the run together and figure out who the true culprit is before the authorities catch up with them.
