Due to some unforeseen events Cloudsdale Weather Factory has run out of water to make rainclouds and Ponyville pegasi are asked to raise water from their local highland reservoir once again. They have less than a day to accomplish said task, and Rainbow Dash is more than willing to give quick refresher training for Ponyville pegasi so they could create the needed tornado in time.
But there is one new pegasus in Ponyville, one that is hesitant to take part in the tornado duty. Or rather an old resident of Ponyville who just recently got her wings. Rainbow Dash insists that Twilight Sparkle must assist in creating the tornado, but the young alicorn isn't confident with her flying skills. Not confident at all. But lack of confidence has never before been a good excuse for Rainbow Dash, and it isn't this time either.
