Rainbow Dash and the girls are performing as the Rainbooms for a gig, but because of some ill-timed forgetfulness (e.g. Rainbow rushing to change from her pajamas to her casual outfit because she’s running late for the gig), she unknowingly goes out wearing NOTHING underneath her skirt, neither her shorts nor her panties.

And it’s only after the band has finished the song that she realizes she’s been going commando in front of the whole audience. Now she must try to get home and put her bike shorts and underwear back on before anyone sees but certain things stand in her way such as strong gusts of wind, neighbor's dogs chasing her, encountering some overexcited fans of her and band as well as some old faces...
