Partisan (2015)

Trained to be an assassin alongside other children, an 11-year-old boy, Alexander, begins to question Gregori's overpowering influence on the children and their training to become assassins. Threatened by his increasing unwillingness to fall in line, Gregori's behavior turns erratic and adversarial toward the child he once considered a son. With the two set dangerously at odds and the commune's way of life disintegrating, the residents fear a violent resolution is at hand in this Sundance award-winning thriller.
