An acquaintance with an attractive young man at a club turns into the beginning of a real nightmare for Aleksandra. She wakes up in an unfamiliar apartment with armored windows, bars and soundproofing, gradually realizing that her new acquaintance, who seemed like the man of her dreams just yesterday, is in fact a cruel maniac who has locked her up. Sasha's only connection with the outside world is a simple tablet with a 40% charge. She tries to write to the police, but understands that she cannot provide anything specific about herself. In the end, she decides to contact her ex-boyfriend Mikhail, who passes the information to his company's security officer Anton. They keep in touch, but both understand that the chances of salvation are melting with every percent of the tablet's battery. She is locked in an isolated space with almost no food, and Anton still cannot determine her location.
