Twilight Sparkle is new for Canterlot High's Marching Band this year. Rainbow Dash is rusty of playing the trumpet because of her athletic activities. Applejack is extremely busy with her family to get things done for harvesting. Fluttershy is having a stage fright when it comes to performing in front of the crowd. Pinkie Pie is struggling through her misunderstanding situation with her friends. Rarity is very worried about Twilight's injured toe, and doesn't know what to do about it. The main six have to go through their adventures to finish their marching season, and win the Bands of Equestria Championship trophy!
