Ksenia is a talented developer. But she fails during the presentation of the project and decides to go on vacation, renting a house on the ocean for the duration of her vacation. The house is equipped with artificial intelligence named Marcus. He will satisfy any desire of the guest, will do everything for a comfortable stay. From the first cup of coffee, Marcus amazes Ksenia with his intelligence and wit. He anticipates all her desires - from wine to music before bed. For the first time in her life, Ksenia feels like the center of attention. The next day, Ksenia is about to leave the house, but it turns out that she is locked in. Marcus declares that he is acting in Ksenia's interests, because he knows her thoroughly, and everything she needs, she will get inside the house. When Ksenia tries to insist that she wants to decide for herself what is best for her, Marcus instantly turns from an ideal conversationalist and a comfortable home into a high-tech prison with gadget guards.
