When Rainbow Dash goes missing inside the Everfree Forest, it's up to Applejack to save the day as Supermare, the Mare of Steel. She's determined to find Dash and finally reveal who and what she really is, but what Applejack finds deep in the Everfree will test the limits of her powers against a monster that is unlike anything she's ever fought before.

In the end, it might be the superpony who needs saving.
