When helicopter pilot Jack Griffiths leaves the RAF to join a private military company, Decisive Measures, he hopes to put behind him forever the brutal ethnic conflicts he witnessed in Bosnia and Kosovo. And to bury the memory of a disastrous mission which ended in the loss of many innocent lives. His new job takes him to Sierra Leone to carry out routine security operations in the diamond fields. Once out there Jack meets Layla, a doctor working with a local charity, but their growing friendship is torn apart when civil war erupts. And Jack is sent back into combat where he has to confront once more the consequences of his past mistake. Then Decisive Measures abandon the mine workers to their fate and Jack and Layla are forced to decide where their true loyalties lie.
