Paul Kersey, a Chicago-area Emergency Room surgeon, lives with his wife, Lucy, and daughter, Jordan. When the family visits a restaurant with Paul's brother Frank, a valet named Miguel photographs their home address from their car's navigation software after hearing about a night they plan to be away from home. However, Paul is called to the hospital that night, and Jordan and Lucy are present when the three armed criminals break into their home. Moments later, one of the invaders is scarred from Lucy and Jordan's efforts to fight back in defense of their lives and home.
