A woman is found in bloodstained clothes on the lonely coast of County Mayo.

At first, she won’t speak. Then a name comes: Ruth. And a story about her missing friend: Maura.

Ruth says she and Maura were staying in a clifftop house together. But there’s no trace of her there. Nothing but a pool of blood.

Ruth says the pair fought in the days before Maura disappeared. But the locals say they only ever saw one woman.

Ruth swears she’s telling the truth, but do the answers really lie in everything she didn’t say?
