On a dark and stormy December night my family are gathered at an isolated hotel in the English countryside. We're reuniting for the first time since the accident that shattered our lives ten years ago. It's a time for love and forgiveness. But more than one guest has an ulterior motive:

The perfect daughter . . . The alcoholic

The single mother . . . The liar

The handsome husband . . . The adulterer

The beautiful sister . . . The jealous sibling

The murderer . . .

As the clock strikes midnight, one member of our party is found dead at the foot of the grand marble staircase. Everyone is a suspect. But which one of us is a killer?
