Sissy Buttons is sassy, smart, and bossy, and can do almost anything - except for things she doesn't want to do. After a tough day playing with her teddy bears in the garden, Sissy's mother asks her to clean up. Reluctant to do so, Sissy falls asleep instead. But in her dreams she finds herself in charge of a real teddy bear picnic. The bears are misbehaving, and unless she can persuade them to try a little harder, everything will go horribly wrong. Sissy finally convinces the bears that they can do anything they want - if they only try!
