Takakura So (Oguri) witnessed his father's murder at a young age. Pledging to catch the killer, he grows up to become an elite cop in New York City, where the criminal lives. His character is cool-headed and disciplined, yet adapts well. Because of major drug dealings, he gets sent to Tokyo to conduct a joint investigation with the Japanese police. There, he gets teamed up with, Kudo Maruo (Mizushima), a detective from a special investigative division. Kudo is a hot-blooded fighting expert due to his earlier days as a delinquent, but he makes a strong impression with his stylish appearance and is always interested in going on group dates. His personality, interests, and investigation methods are completely mismatched with Takakura's, but the two somehow work together to crack the case they've been given. With the appearance of a woman who apparently lost all her memories yet seemed to be greatly linked to the murderer of Takakura's father, the story of the worst,yet the best, partnership between the New York elite and the Japanese detective begins...
