Doll Stripe was a lead acrobat working in a traveling circus until his inability to work with others destroys everything he's ever known. In an attempt to regain what he lost, he meets five diverse and, if you ask him, possibly insane ponies which he must somehow get to work together and overcome their elements of disharmony in order to save everyone in Equestria from a new threat. Will they learn to conquer their flaws before the rest of Equestria suffers?
