Julien Villandrit owns a textile factory whose manager, Henri Corrandi, is his childhood friend. Both love the same woman, Régine de Bettigny, who grants her hand to Villandrit. Mad with jealousy, Corradin will use all means to break up the couple: he does not hesitate to compromise Régine, to send Julien to prison for a crime he did not commit, to spread misfortune. But despite a long and painful separation, Julien and Régine will find each other, still bound by the same love.
