Grajski biki is a 1967 Yugoslav film directed by Jože Pogačnik.
The film is a somber social drama in which war orphans rebel against teachers and authority figures in their reform school.
It stars Danny, a teen punk who organizes a breakout, only to become a victim of the code of toughness by which he lives.
Sex and violence are included in the sometimes confusing story that appeared at the Mannheim Film Festival in 1967.
