John and Elizabeth Dunville believe they have the ideal family. Their three daughters - beautiful, vivacious Baby, clever, industrious Becky and lively, mischievous Brona - attend Dublin's most prestigious convent school and have bright futures - until one night one of the girls slips out into the December fog and doesn't come home ... To the outside world we were this perfectly contented happy family - a mother, a father and three little girls. The truth? Really it was a conspiracy of silence - everyone living a life on the surface while underneath reality bubbles away - until the day it blows up.
