Every night Mrs. Ofelia counts sheep to get to sleep: one, two, three and so on. When she gets to 18 she falls fast asleep. Sheep 19 never gets a chance to jump over the fence. Disheartened and disappointed, she decides to take things into her own hands! Will Sheep 19 and her companions Sheep 20, 21 and all the others over 18, get a chance to jump over the fence and help Mrs Ofelia fall asleep as well? A fun story about fairness and cooperation!
