"Kill List" opens on a small dinner party. Jay and Gal, two average looking English blokes, eat a lovely meal prepared by Jay's wife. Gal has a new lady friend by his side. The friends laugh and, by all appearances, enjoy a happy night. Slowly but surely, marital tension begins to seep out of the glances between Jay and wife Shel. The creep of caustic remarks mixes with a healthy flow of alcohol before eventually erupting into a full-bore domestic incident. Gal, obviously familiar with this scene, acts quickly to settle his friends' young son, and to defuse the near-violent exchange.
