In the 1970s, a member of the IRA takes over an Active Service Unit in London after his wife is accidentally shot dead in Ireland. The unit's mission is to cause chaos and destruction, while his personal aim is to hunt down his wife’s killer — an SAS captain, who is also hunting him.

When Ann, husband George, and son Georgie arrive at their holiday home they are visited by a pair of polite and seemingly pleasant young men. Armed with deceptively sweet smiles and some golf clubs, they proceed to terrorize and torture the tight-knit clan, giving them until the next day to survive.
