Sorok Pervy was a typically patriotic Soviet entry in the 1957 Cannes Film Festival. The story focuses in on Isolda Izvitskaya, cast as a courageous Revolution-era female sharpshooter. While escorting a male White Russian prisoner back to her own lines, Isolda and her captive are marooned on a desert island. Predictably, a romance blossoms between the two former enemies. Unpredictably, Isolda is forced to make a daunting sacrifice to rescue her lover from punishment at the hands of the Czarists. The film is based on a novel by Boris Lavrenyov, previously filmed in 1928 by Yakov Protazanov..~ Hal Erickson, All Movie Guide
