Three stars appear in two separate but intertwined stories of romantic triangles gone wrong in this ambitious drama. In the first segment, Hagolin is a loutish construction worker with an unhappy wife, Eponine. The wife becomes involved with a swarthy working man, Larnier, and their passion knows no boundaries of caution or safety. Eventually, Eponine's and Larnier's lust drives them to madness, and they murder Hagolin. The second tale concerns an up-and-coming young lawyer, Claude, whose mentor is a highly successful veteran attorney, Lamerciere, with a beautiful young wife named Florence. Claude finds himself defending Larnier and Eponine, while Lamerciere dies of a heart attack after he discovers that Florence has been unfaithful to him with Claude.
