Ex-mercenary Sonja Kurtz is out for revenge after her daughter Emma is assaulted by an abalone poacher while on a beachside holiday near Cape Town.

When the poacher is murdered, Sonja is targeted by a violent local gangster and must flee the country.

As Sonja leaves a trail of destruction in her wake - from the threatened wilderness of Zimbabwe to the treacherous beaches of northern Mozambique - a concerned Emma must find the courage to rescue her mother.

But is Sonja a cold-blooded killer? Or is there a darker conspiracy taking place in southern Africa's underworld - one that will change their lives forever?
