The furious water stream threatens to cause a collapse of the metro tunnels and, moreover, the destruction of the whole city.

Garin fights the disaster, trying to rescue the surviving passengers, including … the lover of his wife. Garin has to overcome resentment, anger, and fear. He must survive in order to regain his love, his family … his earlier happy life..
