Rainbow Dash meets a fan of hers at a Wonderbolts event. Being so awesome and totally able to help, the filly begs her to look for her lost brother; she even knows where he might have gone! But Rainbow feels the local police would be more helpful, sends her away and thinks nothing more of it.

That is, until the filly goes missing as well. Now a conscience-stricken Rainbow must track her down to a desolate peak shrouded in an eternal storm, to the remains of a decrepit factory, and endure the horrors within to save her.

A re-imagining of one of our favorite, classic stories: "Rainbow Factory".
