The series "Casting" tells the story of Lena, a lonely librarian who decides to participate in a casting for a role in a new reality show. She is not afraid to experiment, as she has no close people left and, in general, she has nothing to lose. To her surprise, she manages to pass the competition, despite the model competitors with legs up to their ears. But the organizers ask her for one "little thing" - to improve her appearance a bit on the operating table. However, along with her face, Lena is afraid of losing herself.
