Light Up! (2017)

Alevtina Romanova is a warden in the woman's colony, and the only thing that is different from her «iron lady» image is her voice - a voice which even a notable opera diva would envy. However, Alevtina has been ashamed of her talent since the times she was a kid and nowadays, preliminarily making sure no one's around, she rarely sings for herself. Despite the fact that Alevtina is trying to stay invisible, one of the prisoners secretly records her singing on video by a cellphone and puts it online. The tape becomes a real sensation, and soon Alevtina is invited to Moscow to participate in the main singing show on national television. A sincere desire to change her life awakens inside Alevtina but she's not ready to compete in the show at all. The only person who could train her voice and prepare her for the performance is that very prisoner, who recorded the video, who turns out to be a singer in the past.
