Two children have been abducted on their way home from school. After several weeks, they are still missing -- and no one knows whether they are alive or dead. The police are certain that ruthless local gangster Vince Formosa is behind the kidnapping, but without proof their hands are tied. Forced to resign following an accidental death in police custody, former Detective Inspector Sep Black knows he's been set up. But how can he prove it - and stay alive in the process? Convinced that Formosa has a mole within the police, Black sets out to expose the traitor, clear his name and wreak revenge on the man who brought him down. In order to do so, he must go undercover and find the missing children. But even the best-laid plans can sometimes go awry.
