London, 1938. Evelyn has only one dream: to become a singer. Fleeing an arranged marriage, she leaves for Singapore in pursuit of a future brighter than the conventions of society could offer her.

Evelyn performs in a Chinatown cabaret to survive, where she meets Joan, a young Australian doctor and avid fan. Little by little, Evelyn and Joan form a close bond that leads to a love stronger than either has ever known.

But history has other plans. The Japanese army invades Singapore, and Evelyn must flee while Joan refuses to leave her patients. From prison camps to the deep jungle, through encounters and tragedies, Evelyn and Joan struggle to survive and to find each other again.
