Arthur is a frustrated, unhappily married teacher. He used to love teaching, and he used to love Gwen, but now it feels as though happiness is an unreachable goal. Life finally starts to make sense again when he meets Merlin, a sixteen-year-old foreign exchange student.
As their student/teacher relationship strengthens, Arthur begins to have decidedly unprofessional thoughts about Merlin, forcing him to reexamine everything he believes in: his career, his marriage, and even his own sexuality.
