Investigator Pavel Frolov gets into a car accident. After that, his life is torn into two parallel realities — in one of them his son Kirill survived the disaster, in the other his wife Svetlana. Every morning, when Pavel wakes up, he finds himself alternately, in reality with his son, then with his wife. In each of these lives, he tries to find out who or what is behind the accident in order to try to connect the two realities together. And at the same time, to return the respect of his son and the love of his wife, to whom he often preferred work before.
