In 1970s Britain, Dr. Robert Laing (Tom Hiddleston) has just moved into a state of the art high-rise development. It has everything a person would need, including social strife. The middle class tenants like Richard Wilder (Luke Evans) resent the upper class dwellers like Pangbourne (James Purefoy), and vice-versa. Laing is able to stay removed from the fracas for a bit, and strikes up a relationship with single mom Charlotte Melville (Sienna Miller) and Richard’s pregnant wife Helen (Elisabeth Moss). However, the bitterness between the classes eventually explodes into all-out chaos.
