A tense, claustrophobic horror film from writer-director Neil Marshall, The Descent follows a group of six women on a caving expedition in the Appalachian Mountains that quickly turns into a nightmare when they become trapped deep underground. Led by thrill-seeker Juno, the friends attempt to find a way out through an unexplored cave system, but mounting fear, personal tensions and dwindling hope begin to tear the group apart before they realise they are not alone. Marshall combines relentless suspense, pitch-black atmosphere and brutal creature effects to create one of the most effective modern horror films, balancing psychological trauma with savage survival horror.
