Liakos is a poor shepherd boy who is in love with the beautiful village girl Diamanto, who reciprocates his feelings, but her mother does not want the brother of her husband's murderer as her son-in-law. When one day a wealthy local landowner, Lampis, asks for Diamanto's hand in marriage, her mother rushes to give her to him, unaware that Lampis is taking revenge on Liakos, whom Maro loves and with whom he himself is in love.
