The Stolen (2017) on Netflix

The story of a woman who must find her kidnapped son, navigating a world she doesn't know, on the edge of danger with every heartbeat.

Charlotte Lockton, a wealthy, upper class, English immigrant, chooses to forgo all of her home luxuries to find her kidnapped baby son. She navigates her way through the unruly and wild world of the gold rush in 1860's New Zealand, finding unlikely friendship amongst the hustlers, whores, Maori Warriors and Chinese Miners. But in the end, she must face the man who took the boy - and become the woman she never thought she'd be.
