The sky is cloudy when Jack and Annie arrive on the Prairie. They reach a small schoolhouse with only three students. The teacher invites them to join their reading lesson. After the lesson, they are heading back home. The colour of the sky turns green when they come head to head with a strong twister. They must return to the schoolhouse to warn the teacher and students. However, the roaring twister comes closer and closer. Will they make it to the schoolhouse?
