The secret becomes clear when a radiation disaster is reported on television in the morning. Now the businessman Alexander has to save both a broken family and his mistress with a small child.

Businessman Alexander lives a secret double life. He has a family and a mistress with a child. Alexander has long had no intimacy with his wife Svetlana. Stepson Grigory, feeling unloved, increasingly removes from the family, coming under the influence of death groups on the Internet. One morning a radiation alarm is announced on TV. Alexander, Svetlana and their daughter Nastya go down to the basement. But Gregory refuses to go with them and locks himself in the bathroom. Alexander is unable to reach his mistress and confesses to Svetlana that he has other family. The hero says that they need to be taken to a shelter too. He leaves for a mistress with a child. The shocked wife goes upstairs to get her pillows and discovers the body of a suicidal son in the bathtub. She finds a gun in Alexander's safe, sends her husband the last SMS, and goes down to her basement with a gun. In the middle of the journey, Alexander learns that the announcement of the radiation threat was false. He call his mistress. She answers. It turns out the mistress was asleep the whole time and didn't hear the alarm. Alexander reads his wife's suicide SMS and rushes home. Unaware of the cancellation of the anxiety, Svetlana decides to shoot her sleeping daughter, because Svetlana believes that they will die in agony from radiation. Alexander rushes home in his car to save his family.—Ivan Smirnov
