One man holds the key to the hottest secret in our history

This classic Australian suspense thriller centres on the fall-out from A-bomb tests around Maralinga in the early 1950s. Harvey Denton (Colin Friels) is an apolitical cameraman drawn into a conspiracy after finding his father, an army photographer, compiled visual evidence of military wrong-doing in the tests, and sets out to find the missing films. Jack Thompson, an ASIO agent, pressures him not to get involved; but an eccentric scientist (Donald Pleasance) spurs him on with stories of the thousands of veterans, aborigines and families who were adversely affected.
