Plot
Three years ago, Wu Gang was killed by a drug trafficking organization led by the elusive "K". His son, Wu Zhen Feng in an attempt to seek vengeance, unintentionally blows an undercover police operation and causes his best friend Chen Yu to be demoted from the narcotics unit. Taking matters into his own hands, Wu Zhen Feng boards the bus to the border while Chen Yu chases after him relentlessly. Along the journey, the two are almost kidnapped. While separated, Wu Zhen Feng is saved and brought away by militant drug traffickers, and there has been no news of him ever since.
Three years later, Chen Yu has since rejoined the narcotics unit working on a case he believes to be linked to Wu Zhen Feng. When the two finally meet again, Wu Zhen Feng has become a murder suspect who goes by the nickname "Brother Feng". Ignoring his superiors, Chen Yu sets out to find the truth behind all of the conspiracies and clear Wu Zhen Feng's name, but he quickly discovers that Wu Zhen Feng's return has another purpose. The two former best friends begin a game of cat and mouse. Who's telling the truth and who can you really trust?
