A man investigates the circumstances of his father's death thirty years ago. A series of seemingly unconnected events causes disorder in the life of cameraman Harvey Denton: he finds himself caught up in international polities and secret service activities - and it all began during the atom bomb tests conducted by the British in Australia in the fifties and sixties.
The body of bis father - a documentary filmmaker - is found. Allegedly he drowned at sea. According to Royal Commission reports, a highly radioactive aircraft was discovered, containing a body which was identified as Carl Denton. An unsolved murder. Harvey Denton asks questions but is confronted with a wall of silence and himself put under surveillance and threatened. The search for the truth becomes a search for a missing roll of film, shot during the bomb tests by Carl Denton. Both the British and Australian secret services are vehemently interested in the piece of film. Harvey Denton has to find this film before the Royal Commission's term of office expires.
