Twingo and Maria start going out, until Soviet Colonel Piniev Louis Calhern reports to Hooky, announcing he is searching for a Russian ballerina named Olga Alexandrova, aka Maria Buhlen. Piniev assures Hooky that he means no harm to Olga, and that it is his order to bring her back to the Soviet Union. Later that night, Maria and the Mother Superior reveal that Maria is Olga, the daughter of Soviet dissidents. Shortly later, the Soviets search the entire convent, looking for Olga. Hooky does not reveal that he is aware of Olgas presence, not wanting to put the Mother Superiors image in danger. However, after the Russians leave without having found Olga, Hooky announces that he will turn her over to the Soviets the next day. After he observes Twingo trying to help Olga escape, an attempt that Olga declines because she does not want to endanger Hooky and Twingos friendship, Hooky turns her over to the Soviets that night.Over the next few days, Hooky is heavily criticized for his actions by Twingo and the Mother Superior. He and Twingo continue their repatriation duties and they announce to the Soviet Professor Serge Bruloff Konstantin Shayne that he is about to be deported Bruloff reacts by shooting himself. Hooky claims that there is no connection between Olgas reluctance to be deported to the Soviet Union and Serges suicide, until the third person on his list, Helena Nagard Tamara Shayne, Serges wife, responds by bursting into tears. Hooky starts to doubt the policy of the Soviets and as he witnesses Olga being deported to a harsh detainment camp, he swears to raise awareness of the way these displaced people are being treated. ........
