The story of the Podolsk cadets’ heroic stand outside Moscow in October 1941. Cadets were sent to the Ilyinsky line, fighting alongside units from the Soviet 43rd Army to hold back the German advance until reinforcements arrived. Hopelessly outnumbered, young men laid down their lives in a battle lasting almost two weeks to obstruct the far superior German forces advancing towards Moscow. Around 3,500 cadets and their commanding officers were sent to hold up the last line of defense outside Moscow. Most of them remained there for eternity.
On TV a new reality show, "Pionerlager", has started. Following the results of a casting, five young men and five girls, led by young TV presenter Alice Ten, go to the thrown pioneer camp. The rules state that every week someone would be eliminated from the show. The last one remaining will win the main prize: one million roubles. But suddenly game rules change: the invisible observer declares that it is life, not money, that will be the award for the winner. The maniac hiding behind the mask of a horse, begins a hunt for the participants. Children's horror stories which he once listened to in pioneer camp, revive and become a plot of its own murders.
