Fifteen-year-old Tracey Berkowitz is naked under a tattered shower curtain at the back of a bus, looking for her little brother Sonny, who thinks he's a dog. Tracey's journey leads her into the dark underbelly of the city, into the emotional cespool of her home, through the brutality of her high school, the clinical cat and mouse games with her shrink and her soaring fantasies of Billy Zero--her boyfriend and rock 'n' roll savior. Her travels also put her in contact with the seedier inhabitants of the city. Like Lance, her would-be savior who ultimately puts her life in jeopardy. Tracey's stories begin to intertwine truth with lies, hope with despair as she moves closer to the truth of Sonny's disappearance.
