An absurd misunderstanding separated Alina and Maks, who were in love with each other, for 15 long years. Alina ran away from her hometown and gave birth to a daughter in secret from Maks, but she died immediately after birth - so the doctor said. At a school reunion, they met again for the first time, but the conversation did not work out. In addition, Alina's former classmate Tatyana, with whom she was supposed to spend the night, was urgently called to work at the orphanage - her pupil Sonya had disappeared.
