Kyiv, 1968, the end of the 'thaw'. Yura - a physics student, a successful Komsomol leader, a promising novice scientist - falls into the grip of difficult circumstances and the hell of his own doubts. He needs to make a moral choice, and he feels that he is not ready for it. After all, his life is a kind of buffer between two worlds - on the one hand, the world of "golden youth", children of secretaries of the CPU Central Committee, LKSMU Central Committee, KGB, and on the other - the world of his mother Klavka, who is one of those nameless and unheroic representatives of Ukrainian intelligentsia, holding on their shoulders a powerful rear of the sixties.
