If your children were forced to testify against you, what terrible secrets would they reveal?

Moscow 1945. As Stalin and his courtiers celebrate victory over Hitler, shots ring out. On a nearby bridge, a teenage boy and girl lie dead.

But this is no ordinary tragedy and these are no ordinary teenagers, but the children of Russia's most important leaders who attend the most exclusive school in Moscow.

Is it murder? A suicide pact? Or a conspiracy against the state?

Directed by Stalin himself, an investigation begins as children are arrested and forced to testify against their friends - and their parents. This terrifying witch-hunt soon unveils illicit love affairs and family secrets in a hidden world where the smallest mistakes will be punished with death.
