Dao Ba Khang has left war-ravaged Vietnam and settles in Australia with an Australian wife and family. One day he discovers that his skin has turned black. He thinks to hide among tribal Aborigines in the Australian outback, but finds as he progresses on his journey that they too have been made victims of a tragic fate - annihilated by British nuclear testing and deprived of their land.

Written in the 1970s, Manhunt is the first novel of B. Wongar's Nuclear quintet.
