When Rainbow Dash's folks are gone, she raids their liquor cabinet. Unfortunately for the poor students of Canterlot High, the inebriated Dash finds her way to school. All reason is lost as the star athlete goes missing after her friends confront her about her being drunk. It is up to Sunset Shimmer and the others to find Rainbow before something bad happens.

There is one thing on everyone's mind as the search throughout Canterlot High widens, "Where in the world is Rainbow Dash?"
