In September 1945, Captain Chuck O'Donnell and the aircrew on board the B-29 transport known as Daisy Mae, were ordered to fly from Darwin to Learmonth, with seven Australian nurses on board, but were diverted to Broome for engine repairs. The nurses, led by Jenny Hopkins-Jones, were sent on to Perth, and the B-29 was ordered to return to Darwin. Daisy Mae never made it. During the previous months, Chuck and Jenny had become very close, meeting frequently in Port Moresby. When Chuck was reported missing Jenny was devastated, as she was pregnant with their daughter Elizabeth, who grew up and joined the Australian Military Intelligence Organisation (AMIO). Elizabeth became involved in the search for Daisy Mae, meeting Commander Tony Dowling on HMAS Murray, near Cockatoo Island. Someone had definitely covered up the disappearance of Daisy Mae, by frustrating the search, murdering any witnesses and altering vital records. Three decades later, still stone-walled by US Military Security, and unable to tell her mother anything about the work she was doing, Elizabeth eventually unravels the cover up surrounding B-29 Daisy Mae. She is almost killed in the process to reconcile her family, conquer deep personal anxieties and close the file on a missing atomic device. A year after the attack on Pearl Harbour, some general officers based in Washington DC, who had lost sons and other relatives fighting the Japanese forces, were actively seeking revenge. The covert establishment of a special atomic device assembly unit, during the Manhattan Project at Los Alamos, was a desperate strategy by four very senior officers to kill the Japanese Emperor and military leaders. The team of highly skilled scientists and technicans, who had been secretly coerced to join the assembly team, or risk criminal exposure of their homosexuality, ensured that the device, known as TOK-3 was effectively assembled and made ready for use. Along with two other atomic devices that were ultimately dropped on Japan, TOK-3 was secretly despatched to Tinian, in the South Pacific. Following the surrender of the Japanese, TOK-3 could not readily be deployed and was securely packaged to be returned to Los Alamos. It was flown to Darwin on Daisy Mae, a B-29 transport. The sudden disappearance of Daisy Mae ameliorated the ongoing covert operation, although Major Sam W Bima from MILSEC ensured that any possible witnesses were eliminated and the possible crash site re-positioned many miles away. Despite the stalling and misleading activity by the US Navy, the crash site of Daisy Mae was finally discovered near Cockatoo Island, in the Kimberley Region of Western Australia. However, a coordinated search with the Royal Australian Navy revealed that there was no atomic device on board the wreckage and that there was only confirmed evidence of four aircrew, when five aircrew had left Darwin. Was the missing airman Elizabeth's father?An investigation by MILSEC in Washington DC failed to find any additional information on the whereabouts of the atomic device, or the missing airman. Elizabeth was continually frustrated by the lack of finality, but was always extremely uncertain about her reaction to any revelation of the identity of the missing airman. The efforts by Elizabeth to find her father and reunite him with her mother, notwithstanding the desperate actions of now retired Sam W Bima, create a dramatic finale.
