Post war trials of collaborators in Ukraine

Village (unidentified, in Ukraine). Women are beating a prisoner [the prisoner may be Zvarych: a well-known Ukrainian collaborator, this needs further research and documentation]. Someone behind the camera interviews a man. CUs of an interviewee. Another man is testifying at the Soviet court. CUs of witnesses testifying, CUs court documents, CUs judges. Translation of Russian narration and Ukrainian testimony (Russian is dubbed over Ukrainian, both are heard): As children our parents would frighten us with "Zvarych." "You'll see, the 'red boots' will come." Zvarych was the "red boots." [At the court] -What was the role Zvarych played in mass execution of Skalat(?) civilians? [Skalat it is assumed, is a town in Western Ukraine, although this needs to be confirmed.] - It seems to me he was there. Yes. He shot. - [unable to decipher words, the audio is not clear] - He was a good policeman. One hundred percent policeman.
