When a high level Japanese criminal is brutally executed, his family puts a hit out on the assassin who pulled the trigger. But when a lone hit man (Li) hears of a reward, he teams up with an "agent" willing to show him the underworld of Japanese corruption in order to cash in on a murder.

Now, the best hitman money can buy is about to discover the person no one would have expected.

Enter a world where watching your back becomes the only means of survival.
