As Detective Inspector Helen Grace's best friend fights for her life, the man responsible flees the country. An international manhunt leads to the Dutch port city of Rotterdam, where crime is big business.

With the underworld harbouring one of its own, the local police closing ranks against an outsider, and a pair of trained assassins shadowing her every move - Helen is all alone. Far from home - and closing in on a killer - she must rely on her instincts, her drive for justice, and her thirst for revenge. Can she track down her target before he escapes forever? Or will she see her life and everything she loves left in ashes...?
