The Equalizer S04E13 - Lullaby of Darkness

A psychopathic stockbroker, Joseph Morrison, is a habitual wife- and child-abuser who ruthlessly beats & humiliates his family. Because of his money & influence, he is able to avoid accountability for his actions. One night a neighbour in his apartment complex hears him attack his family, and she calls in The Equalizer. Morrison, however, hits McCall with a restraint order, and files a malicious lawsuit against his neighbour in retaliation for reporting him. McCall strikes back, however, by obtaining a video of Mr. Morrison's child giving grim details of physical abuse.
