Daria Smirnova’s life—a talented doctor and caring mother—falls apart after an accident: her daughter Anna urgently needs a kidney transplant. Dasha’s husband, who could have become a donor, cowardly runs away. In desperation, Daria is confronted with a monstrous proposal from her boss Sergei, who is in love with her: to forge documents and give Anna an organ intended for another patient. Daria refuses, but Sergei acts without her knowledge. After the operation, he blackmails her, demanding reciprocation under threat of exposure. Believing his words that the other girl was unharmed, Daria breaks off the relationship with him and moves to another hospital. However, Sergei lied: the patient died, and her brother is looking for those responsible. Will Daria be able to prove her innocence?
