Watch on 123Movies. House of Rules is a short thriller set on a storm-soaked night in mid-1980s suburbia, where a bored group of friends discovers an ancient “murder mystery” game hidden in a dusty storage closet. What begins as ironic fun turns deadly when the ritual assigns one player a real knife, another a loaded gun, and seals the house as it becomes a living game board that punishes rule-breaking with blood. As the first death occurs without a hand laid, the group realizes escape and outside help are impossible—and that judgment must be carried out to restore balance and they have no choice but to finish the game!
