Walnut Grove is held in the grip of terror when the three Galender brothers move into town. Before long, the bullying brothers have run up enormous bills that they refuse to pay, spread malicious and injurious lies, and beaten up anyone who gets in their way. The limit comes when the brothers try to sexually assault Caroline Ingalls -- and when the girl's father, Charles (
Michael Landon), confronts the boys, he is pummeled for his troubles. It ultimately falls to the schoolchildren of Walnut Grove to end the Galenders' violent rampage once and for all. ~ Hal Erickson, All Movie Guide
