Prison Diary.

Maria Zhukova is invited to study in the USA. During her studies, Maria accidentally learns information that calls into question all her ideals and beliefs. Starting her own investigation, she finds out that she is involved in a big multi-way game related to the threat to Russia's security. Taking the risk and obtaining evidence, Zhukova does not have time to leave the United States, and she is arrested. The girl ends up in prison — with a long stay in solitary confinement, psychological pressure, torture and interrogations by the FBI, persuading her to stay in the United States and condemn Russia.
