The parents of a girl who was killed by a savage dog are granted the opportunity to spend three days with their deceased daughter.

In a post-apocalyptic wasteland, a woman rebels against a tyrannical ruler in search for her homeland with the aid of a group of female prisoners, a psychotic worshiper, and a drifter named Max.

Still grieving the death of nine-year-old Alice - their only child - at the jaws of a crazed dog, vet Patrick and pharmacist Louise relocate to the remote town of Wake Wood where they learn of a pagan ritual that will allow them three more days with Alice. The couple find the idea disturbing and exciting in equal measure, but once they agree terms with Arthur, the village's leader, a far bigger question looms - what will they do when it's time for Alice to go back?
