Greek lessons

In a classroom in Seoul, a young woman watches her Greek language teacher at the blackboard. She tries to speak but has lost her voice. Her teacher finds himself drawn to the silent woman, for day by day he is losing his sight. Soon they discover a deeper pain binds them together. For her, in the space of just a few months, she has lost both her mother and the custody battle for her nine-year-old son. For him, it's the pain of growing up between Korea and Germany, being torn between two cultures and languages.
