A group of Americans travel to Moscow coinciding with an alien invasion of the city. Thermometers mark 40 degrees during the most intense heat wave in Moscow’s history. Two young men are looking for cover under an abandoned police car on Red Square, now completely deserted. They are not looking for a shade to ward off the sweltering heat. They try to avoid being located by camouflaged aliens who have colonized the city. For some days, these young people and their companions have been forced to seek shelter underground, since the city, like the rest of the world, has been decimated by an alien threat. Now they have to hide, have few supplies and desperately seek safety, something difficult to find even in the biggest tourist attraction of Moscow.
