Gene Kelly is a legend of the heyday of the Hollywood musical. His name stands for masterpieces such as "Singin' in the Rain" and "An American in Paris". As a singer, dancer, actor, choreographer and director, he was a true all-round artist who revolutionized the world of dance in particular. Kelly, who loved to experiment, explored new forms of dance expression and helped a whole generation of young talents to fame. From his beginnings in cabarets and on Broadway to his recognition as a choreographer and director, the documentary shows how the good-looking star with a charming smile expanded the boundaries of dance expression: He danced in the open air in the streets of New York, with a cartoon character or his own reflection. But this dazzling entertainer image should not obscure the fact that Kelly, as a staunch supporter of the American civil rights movement, also saw dancing as a political statement.
