A large, carefully plotted "cash-in-transit" raid goes hopelessly awry when armed policemen intervene to seize the perpetrators. Relatives and friends of the incarcerated are convinced that information -- the date, the time -- was leaked by the only man to escape before his arrest. Deputy Constable Colin Harpur and Assistant Constable Desmond Iles are delegated the job of hiding and and protecting the informant and his family. With an unruly informant - whose reckless behavior serves to aid an angry mob - on their hands, Harper and Iles find themselves faced with their toughest assignment to date - one that is only resolved in the most brutal and astonishing turnaround that the deputy constable and assistant constable have ever seen.
