People call Ray Infantino when they need a private investigator to find a missing person.But what happens when someone with bad intentions comes looking for him?
PI Ray Infantino searches for a missing girl in San Francisco, the city he abandoned years ago after his fiancé was killed. Thrust into his old city haunts, Ray finds that Tania may not be lost at all. Tania saw a murder; and a criminal gang, the Black Fist Triad, wants to make sure she never sees anything again. Ray enlists help from an old flame, Dominique, but now he has three women on his mind. Meeting with various witnesses—ex-cops, prostitutes, skinheads—he relentlessly tracks the evidence. But the hunt for Tania fires his obsession with avenging the murder of his fiancé. When the triad retaliates, and blood begins to flow, Ray must walk the knife edge between revenge and redemption on the streets of San Francisco.
