In Post-World War II London, Jean Paget, a secretary in a leather goods factory, is informed by solicitor Noel Strachan that she has inherited a considerable sum of money from an uncle she never knew. But the solicitor is now her trustee and she only has the use of the income until she inherits absolutely, at the age of thirty five, several years in the future. In the firm's interest, but increasingly with personal interest, Strachan acts as her guide and advisor. Jean decides that her priority is to build a well in a Malayan village.
The second part of the story flashes back to Jean's experiences during the war, when she was working in Malaya at the time the Japanese invaded and was taken prisoner together with a group of women and children.
As she speaks Malay fluently, Jean takes a leading role in the group of prisoners. The Japanese refuse all responsibility for the group and march them from one village to another.
