Sweetie Belle feels like her life has no purpose, and that she's an outcast among her fellow ponies. These feelings she has no idea where they come from, but it's at a point where she can't enjoy anything. Even spending time with her friends makes her feel isolated, and there's still that nagging feeling that she should be doing something else.

Little does she know how right she is. She is very different from her fellow ponies, but the answer to her question just brings about more questions. Where did she come from? Who made her? Why was she made? She'll have to figure some of this out very soon.

Because unfortunately, she isn't alone...

And the others... aren't as friendly as she is...
