1920, rural Ireland. Anglo-Irish twins Rachel and Edward share a strange existence in their crumbling family estate. Each night, the property becomes the domain of a sinister presence (The Lodgers) which enforces three rules upon the twins: they must be in bed by midnight; they may not permit an outsider past the threshold; and if one attempts to escape, the life of the other is placed in jeopardy. When troubled war veteran Sean returns to the nearby village, he is immediately drawn to the mysterious Rachel, who in turn begins to break the rules set out by The Lodgers. The consequences pull Rachel into a deadly confrontation with her brother – and with the curse that haunts them.

Rachel, a rookie cop, is about to begin her first night shift in a neglected police station in a Scottish, backwater town. The kind of place where the tide has gone out and stranded a motley bunch of the aimless, the forgotten, the bitter-and-twisted who all think that, really, they deserve to be somewhere else. They all think they’re there by accident and that, with a little luck, life is going to get better. Wrong, on both counts. Six is about to arrive – and All Hell Will Break Loose!
