Boys (2015)

Markus is in an institution for young sex offenders. He is a shy boy whose face tells wordless stories. There is no physical proximity at the institution, so the inmates wrestle. It is a place where skinlessness quivers in the air. Markus's only friend in the institution is the wayward, violent Tobias. Markus's trial approaches, and then Tobias will find out why Markus has been locked up.
