In school they sat at the same desk: Regina and Alice. Bagira and Lysa. Friends-rivals. One is smart, the other is cunning. At first, Alice thought she had outsmarted Regina. Lysa rejected poor student Anton and married a promising businessman Arseniy. Regina picked up what was left — her best friend’s ex-boyfriend. But it was her husband who suddenly got rich, while Arseniy was almost ruined. Alice envied her friend: she had a шикарна apartment, a personal masseur, designer clothes — and didn’t have to work to have all that. And she herself was struggling, gradually turning into an old woman. And then she came up with a plan to get everything back. After all, she’s cunning — no wonder she got the nickname Lysa at school. She only needs to lure her friend into a trap, set the house on fire, and hide the corpse under the burned logs. But Regina had her own plans too. The plan succeeded for only one of them. But who survived — Bagira or Lysa? What won — mind or cunning?..
