Every twenty years, they return.

Demons? Aliens? No one knows for sure. But this time, they're ready. Or are they?

Justin Adams thought he had a plan. Twenty years to prepare for the next Cleanse - the night the creatures come back. But one bad gamble and he's lost everything. Now his family's survival rests on a small metal box, a few borrowed guns, and a promise he's terrified he can't keep.

Across town, millionaire Rupert Bainbridge watches from his mansion. For him, survival is guaranteed - but even steel walls can't keep out guilt, madness, or the cult gathering at his gates.

As the world braces for the bloodbath, neighbours will turn, secrets will surface, and the true nature of the Cleanse will be revealed.

A brutal apocalyptic horror with a sprinkle of Snatch, for fans of The Purge, 28 Days Later, and The Mist.

Welcome to Judgement Day.
