New York City, 1998
A lowlife dealer and an ex-gangster member, Robbie Gong, working with his old friend - Mr. Nijima, the Mathematical Professor, to solve a murder that the NYPD can't even solve by any means. Rumor has it that Gong's only daughter killed by his own gang's executioners. But as much as the investigation and kidnapping happened, Robbie and Nijima's motives suddenly wrapped up the reality of their revenge plan into the rabbit hole. When everything solved, there's nothing but a blind revenge for them.
