Cloudsdale has seen its fair share of storms in the past, but the biggest one is about to make cloudfall right on top of the city should the Wonderbolts not scramble their Weather Patrol immediately. Lightning Dust and Thunderlane are assigned be the first flight of ponies heading into the heart of the storm to start dismantling it from it's core. When they get inside, however, things take a turn for the worst and Thunderlane ends up having to not only save his friend, but also discover a feeling that he hasn't felt before in his life.
