Rainbow Dash woke up to check on the Weather Machine in the Weather Factory and met Lightning Dust in the factory, and went swimming with her friends, but the next day, she went to visit Twilight, but she was not there; Spike told her she was at Applejack's so she went there. After a while, they heard a loud boom outside, a stormy cloud destroyed Applejack's 2 apple trees, she went to the Weather Machine and saw a black figure glitching up everything and escaped but she didn't stop the figure. Then she goes back to Ponyville and saw the weather changing every 2 minutes. Then the weather went crazy and the weather invaded Canterlot, Fillydelphia, Coltorado, Manehatten and many other places. Can Rainbow Dash fix everything before Equestria goes into chaos?
