The action takes place on a Maragata hacienda that is sinking into misery, whose situation can only be solved through a marriage of convenience. But the marriageable girl, during a train trip, falls in love with a young poet and is reciprocated. Her family is opposed to this relationship, since they have promised her to marry a man of good standing.
