Jack is a farm boy, but the dust bowl has taken all the crops away. The rain has disappeared. His sister, Dorothy, is very sick. Jack's father thinks he is a good for nothing little boy and never accepts help from him. Then, one night in the old Talbot barn, blinding light shines from inside of it. Jack goes to explore. There he finds a creature with a face that looks like rain, or rather, The Storm King. Also, in the barn, he finds a bag full of thunder. Eventually, he saves the day and it rains again after years and years of drought.
