Щедрая природа одарила Эша Линкса красотой, а воспитание превратило в жестокого и безжалостного убийцу. Бродяга, принятый в семью «Папы» Дино Гольцине в качестве наследника и секс-игрушки, он достигает возраста семнадцати лет и сбегает из дома, решив взбунтоваться против дьявола, который его вырастил. Но страшная тайна, из-за которой старший брат Эша сошёл с ума в Ираке, оказывается в лапах омерзительного, беспринципного Папы. Поэтому сейчас не самый удачный момент для Эйджи Окумуры, молодого чистосердечного фотографа из Японии, заводить знакомство с погрязшим в бездне проблем Эшем...

Aslan Jade Callenreese, known as Ash Lynx, was a runaway picked off the streets of New York City and raised by the infamous godfather of the mafia, Dino Golzine. Now 17 years old and the boss of his own gang, Ash begins investigating the mysterious "Banana Fish"—the same two words his older brother, Griffin, has muttered since his return from the Iraq War. However, his inquiries are hindered when Dino sends his men after Ash at an underground bar he uses as a hideout.

At the bar, Skip, Ash's friend, introduces him to Shunichi Ibe and his assistant, Eiji Okumura, who are Japanese photographers reporting on American street gangs. However, their conversation is interrupted when Shorter Wong, one of Ash's allies, calls to warn him about Dino. Soon, Dino's men storm the bar, and in the ensuing chaos kidnap Skip and Eiji. Now, Ash must find a way to rescue them and continue his investigation into Banana Fish, but will his history with the mafia prevent him from succeeding?
