An English tourist couple rent a boat to visit the island of Almanzora, just off the southern Spanish coast. When they arrive, they find the island apparently empty of adults. There are only children, who don't speak but just stare at the strangers with eerie smiles on their faces. The English couple soon discovers that all the island’s children have been possessed by a mysterious force, a kind of madness which they can pass from one to another, and which makes them attack and murder their elders, who can't defend themselves because, of course, nobody can kill a child...

The film was highly controversial on its original release in the 1970s and was heavily cut in most countries. This Blu-ray presents the full version of the film but also includes the shorter “Island of Death” release, which does not have the opening documentary footage. The film influenced many subsequent books and movies, including CHILDREN OF THE CORN and was remade in 2012 under the title COME OUT AND PLAY. The version on this Blu-ray is the definitive release of what has come to be recognized as a classic of world horror.
