Sandor Esterhazy is descended from a long line of talented pianists, but has no desire to play. So, one snowy afternoon, he promises his soul to the devil in exchange for a life of his own choosing. Afterwards, he laughs it off as a joke, but that night the devil arrives dragging someone - or something - with him. Uncertain what to do with the bewildered creature, Sandor locks it in the basement, allowing it out only once a night to visit the piano room - the creature, who he names Ferdi, is desperate to play. Sandor slips easily into his new role of captor, but as Ferdi learns what it is to be human, tensions between the two escalate, and Ferdi escapes into the world.
