An Unfinished Piece for Mechanical Piano (Russian: Неоконченная пьеса для механического пианино, romanized: Neokonchennaya pyesa dlya mekhanicheskogo pianino) is a 1977 Soviet drama film directed by Nikita Mikhalkov, who also co-stars.

In the early twentieth century, members of the Russian gentry gather at the rural estate of Anna Petrovna Voynitseva, a general’s widow.

Among the guests are Dr. Triletsky, the creditor Mr. Petrin, Porfiry Semyonovich Glagolev (an admirer of Anna Petrovna), and neighbors Mikhail Vasilyevich Platonov and his wife, Sashenka.

Voynitseva’s stepson, Serge, introduces the group to his young wife, Sofia, whom Mikhail recognizes as a former love.

The film ends with all characters gathering at dawn by the river meadow, concluding with a shot of Petechka sleeping, turning away from the rising sun’s first light.
