"Retaliation," which is set in present-day London, is based on true-life events. It follows the story of a middle-aged man, Malky (Bloom), still trying to come to terms with crippling insecurity, the residue of childhood sexual abuse at the hands of a trusted and idolized priest. The abuse by the priest, the withdrawal of his mother's love and abandonment of God set Malky's life onto a twisted trajectory of violent employment, serial self-abuse and psychotic sexual jealousy.
