Stella is accepted to a private acting school in Berlin. But there is something wrong with the “Matteusz Gdula-Institute”. In the seventies, the school's founder, Matteusz Gdula, practiced a learning style that promised to let students shine by driving them to their mental limits. But his method was banned, as mysterious deaths occurred during his lessons and Gdula committed suicide. In the present, Stella starts to suspect that, behind the closed door to the abandoned, forbidden wing of the school, a bloody secret is lurking.
