The film begins with a story about how an ordinary family made a fortune in Chicago in the 19th century, until a fat woman named Daisy knocked over a lantern and lit a fire, which immediately engulfed the whole city of Windy. As the fire spread, frightened people rushed to the river, and a poor guy was even trampled to the ground by the cattle. The success of the film lies in the reproduction of the Chicago Fire of 1871.
