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

It is 1977, Dublin rocks to the music of Thin Lizzy and the world is stunned by the death of Elvis Presley. Frankie, caught between acne and adulthood, has just completed his final exams in school. Convinced he will fail, he survives the summer organising a beach party, having lustful thoughts about two girls he believes are unobtainable and fending off the advances from a visiting American family friend, all whilst coping with his oddball family.

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?
