As a priest, Thomas is used to hearing the confessions of his parishioners. One afternoon, he listens to the lengthy confession of a girl who is deeply troubled, and over time, her distress begins to unsettle Thomas himself. Thomas finds himself drawn into his own labyrinth, reflecting on what he has done and the things he has let go. The confessional booth transforms into a space of silent inner rooms, with a single beam of light in the corner.
