Cooperation was based on a written agreement-complete with the signature of Lavrenty Beria, head of the notorious nkvd-which is shown in the film.

两者之间的合作基于一份书面协定。在这份协定上，有臭名昭著的苏联秘密警察头子(NKVD，苏联内务人民委员会)贝利亚完整的签名，片中有过展示。

Sometimes the NKVD simply picked Polish-sounding names from the telephone directory, or arrested en masse all those attending a Polish church service.

有时内务人民委员会只在电话号码簿上挑一些发音像是波兰人的名字，或是成批逮捕去波兰教堂礼拜的人。
