Plot synopsis: A group of violently insane individuals escapes from a special-security mental hospital, imagining themselves to be nothing less than Soviet partisans caught in a hostile environment, and the local orderlies, in their opinion, are nothing less than Gestapo agents. This entire gang of hardened mental hospital patients and repeat offenders is led by the schizoid Matvey Matveyevich, nicknamed "Chocolate Bunny."
