Emil goes to Berlin to see his grandmother with a large amount of money and is offered sweets by a strange man that make him sleep. He wakes up at his stop with no money. It is up to him and a group of children to save the day.

Not even on vacation does building tycoon Harald Rehm (Willy Fritsch) look after his son Nils. He would much rather inspect a building site in the mountains or make out with governess Margret (Josefin Kipper). When Nils runs away and promptly gets stuck in the mountains, Rehm has to show some real fatherly love.
