It is late in 1971 in Vietnam and the Australian Army's contribution to the war is nearly over. Mark Ross, a transport company driver, is given the seemingly innocuous assignment of delivering two female personnel, one a local, the other a young American, to their respective destinations in and around Saigon. Ross is looking forward to unloading his passengers and enjoying some unexpected R and R in the big city. But when the exigencies of war, and some of the political intrigue behind it all, intrude to change his plans, Ross's easy-going attitude receives a serious jolt. The experience takes a toll and as well as that, he must come to terms with his feelings for his new American friend and the circumstances of their sudden if inevitable parting.
