Purge (2012) on Netflix

A tormented young woman is given a hiding place by an elderly lady and soon they are reminded of their mutual horrendous past.

The story of two women from two different eras linked by separate tales of deceit, desperation - and fear. Aliide has experienced the horrors of the Stalin era and the deportation of Estonians to Siberia, but she herself has to cope with the guilt of opportunism and even manslaughter. One night in 1992 she finds a young woman in the courtyard of her house; Zara has just escaped from the claws of the Russian mafia who held her as a sex slave. Aliide later finds out that the girl is related to her. Survivors both, Aliide and Zara engage in a complex arithmetic of suspicion and revelation to distill each other's motives; gradually, their stories emerge, the culmination of a tragic family drama of rivalry, lust, and loss that played out during the worst years of Estonia's Soviet occupation.
