A storm on the Caspian Sea lands two friends, sailor Yusuf and mechanic Alyosha, on the shores of Soviet Azerbaijan where they arrive at a kolkhoz (a Soviet “collective farm”). One of the administrators of the kolkhoz is the beautiful Masha who they both fall in love with. Their rivalry for her affections affects their work and threatens the community.

Shot on location in the Caspian region, By the Bluest of Seas is one of the most lyrical and uplifting films of the Soviet era, eschewing propaganda in favor of a comedy about love and friendship. Its ravishing cinematography and excellent performances made Boris Barnet highly regarded by film-makers.
