A typical British family is labeled as murderers by the tabloid press after a dinner guest dies in their home, and a scheming psychotherapist leaks the story to opportunistic reporters. Tom Thompson (Chris Langham) was taking his dog for a walk when he happened across Blake, a man who appeared to have fallen on hard times. Sympathetic, the suburban father invited the stranger back to his home or a hot meal. During the course of the dinner, however, Blake suddenly dropped dead. Months later, a friend of the family relays the perplexing story to his therapist Dr Eric Sacks (Simon Amstell), who immediately leaks the story to the press. In no time, the Thompsons gain a notorious reputation as the, "Family of Killers." Meanwhile, all Tom wants is to gain the respect of his rebellious daughters Jess and Katie, sooth the frazzled nerves of his distraught wife Sophie.
