In Jury of One, French filmmaker Andre Cayatte once more probes into the intricacies of the Gallic justice system. Sophia Loren plays the widow of a man reputed to be a gangster. When Loren's son Michel Albertini is accused of murder, his father's reputation practically assures a guilty verdict. Desperately, Loren kidnaps Gisel Casadessus, the wife of prosecuting judge Jean Gabin. In order to save Gisel's life, Gabin acquits Albertini, only to discover that his wife, a diabetic, has died after refusing to take insulin. It is up to the conscience-stricken Loren to mete out final justice against herself. Jury of One was also distributed to English-speaking countries under the title The Verdict.
