Meanwhile, Irina Garina (Svetlana Hodchenkova) is torn between her lover, businessman Vlad Konstantinov (Anatoly Bely), and her husband, surgeon Andrei Garin (Sergei Puskepalis).

Andrei has to take their daughter Ksenya (Anfisa Wistinghausen) to school but by chance, they take the "Garden" metro station.

Simultaneously, Konstantinov arrives, hurrying to work and forced to park his car because of traffic jams.

Meanwhile, Sergeitch, drinking with casual acquaintance Galina (Elena Panova) next to the "Garden", recalls that the water leaking into the tunnel smelled of slime, which means that it cannot be groundwater.

They are detained by the police for drinking alcohol in a public place but Galina manages to escape, and flees into the subway.

In custody Sergeitch asks for a phone to tell the dispatcher everything, but the police turn a deaf ear to his pleas.

The driver of the train (Konstantin Ovseannicov) that by coincidence contains Garin, Konstantinov and Galina, applies the emergency brake.

The water level rises, a short circuit occurs, and all who did not escape the flooded area of the tunnel die from electrocution.

Garin, Konstantinov and Galina, courier Michael (Stanislav Duzhkinov) and a couple, Denis (Alex Bardukov) and Alisa (Katerina Shpitsa), finally can seek to escape.
