Vinyl Scratch and Octavia Melody are booked to headline the final day of the music festival held in the Grand San Palomino Desert. Already infamous in her partying habits, Vinyl is given strict instructions to not go overboard with her well-known vices for fear of missing their performance. After getting some fun "favors" from a stranger at the festival, Vinyl begins to have episodes that leads to her inevitable transformation into a crazed, horse-form raving DJ about to put on the show of her life at the end of the weekend.
