Two young shipwrecked sailors, the blonde Aljoscha and the dark-haired Yusuf, are stranded on an island paradise in the Caspian Sea. But they soon become rivals for the love of the beautiful Soviet commune leader Mascha.
"By The Deep Blue Sea", the first Azerbaijani sound film, is one of the early works of the Soviet film director Boris Barnet. With a mixture of lyric outbursts and eccentricity, where tragic events are continually interrupted by comical ones, even satirically exaggerated, Barnet portrays social milieus and characters: a Soviet René Clair. However, the subtle mixture of satire and lyric met with little approval from the ruling communist regime. Barnet's main actor actually appears to be nature: the glimmering sun, the calm sea in a golden sunset or metre-high waves - the rough sea being a metaphor for the struggles of the two men.
