Papercut

Sixteen-year-old Perttu, a talented and promising cellist, feels his life spiralling out of control-depression, warring parents, suicide attempts.... He hurts his body to take his mind off the emotional pain. Worried that his playing is suffering because of this, and that he will fail his final diploma exams, Perttu enrolls in private classes over the summer. His new instructor, the mysterious Mr. Manninen, teaches him more than he expected-but Manninen is hiding a terrible secret, one that could endanger Perttu's life.
