In the Deep of Winter (2017)

Her name is Xiao Li. She has believed in God for more than a decade. In the winter of 2012, she was arrested by the Chinese Communist police at a congregation. During interrogation, the police repeatedly coaxed, threatened, battered and tortured her in their attempts to seduce her to betray God by disclosing the whereabouts of the leaders and money of the church. Particularly in one frozen night when the temperature was twenty degrees below zero, she was forcibly stripped naked, drenched with icy water, electrically shocked on her genital, and force-fed mustard water by the police.... She had suffered brutal torture and unimaginable humiliation.
