Spies

Arina dreams of dedicating her life to the Motherland. Zoya wants to escape from the cruel felon Voron. Zoe accidentally becomes an accomplice to the gruesome robbery of Arina's family. Both girls end up in prison.

The girls arrange a transfer from prison into the intelligence agency. Arina gladly accepts the offer. Zoya does as well, but only to avoid punishment. The girls begin to study with the other secret agents in training. Arina excels in all subjects, except for physical training, while Zoe has no problems. Arina despises Zoya during training and attempts to frame her. Zoya manages to elude.

The War begins. The girls are sent on their first mission. In occupied Riga they must find a Soviet scientist, Professor Serebrov, and ensure safe extraction back to Moscow. Arina and Zoya are not happy with their joint assignment, but they don't contest the orders and follow through.

Arina and Zoe stay in Kiev under the disguise of nuns. Their mission is to find a downed Soviet plane near the city. A military engineer was carrying classified documents about the trials of Katyusha on it. The spies must find the plane and destroy the documents, before they fall into the hands of the Germans.

Arina faces a difficult choice. Zoya, whom she hates with all her heart, has been captured by the Germans and needs to be rescued. Arina manages to look past her feelings and attempts to convince a young lieutenant to attack the Germans and save Zoya.
