Raymond, who had been living alone with his father, is reunited with his mother for the first time after his father's sudden death. Having spent the past five years trapped in the shadow of his mother, a famous actress, Raymond is sent to a boarding school in a remote area. Despite its grand, castle-like appearance, the school is more like a prison, filled with students in similar situations to Raymond. As he recalls the past five years he spent feeling like a pet, Raymond is consumed by a desire for revenge. Then, Hugh, George, Simon, and Jerome enter his life. It doesn't take long for Raymond to realise that he's been thrown into a giant cage filled with predators wearing masks of hypocrisy.
