On a mountain lake, in the picturesque Alps in the Salzburg region, the old, rich grumble has retired to his country house and actually only wants to live in peace and seclusion. Soon the longed-for peace will be over, because in the immediate vicinity a home for little-wealthy holiday children will be opened in an empty house, which will be headed by the cheerful and optimistic teacher Miss Helm.
