After an unexpected guest from the future, Nora West-Allen, appears at their home, Barry and Iris must figure out how to get her back to the future without disrupting the timeline - even more than she already has. Team Flash must work together to send Nora back, while simultaneously fighting off another villainous meta.

Okay, let's back up. My name is Nora West-Allen, the fastest woman alive. When I'm from, 30 years from now, I'm the guardian of Central City. I'm a speedster, just like my dad. People call me XS. Every day, I hope to live up to the legacy of The Flash... But I've still got a long way to go.
