Richard Karlsen is a charming and talented young man - the undisputed leader of his circle of privileged South-Dublin teenagers. Straight out of school with a long summer and then university ahead of him, Richard's world seems full of possibility. A new relationship with Lora, whom he meets at a beach party, seems to offer Richard the sort of relationship that he's always been yearning for. But one night, during a party, Richard does something that destroys it all and shatters the lives of the people closest to him.

Winner of numerous international film awards and featuring a breathtaking performance from star on the rise Jack Reynor, What Richard Did is a quietly devastating study of a boy confronting the gap between who he thought he was and who he proves to be.
