When Tina (Jenna Ushkowitz) bumps her head, the world of New Directions is turned upside down in her eyes. Then, New Directions face off against Wade (Alex Newell) and Vocal Adrenaline at Nationals in Chicago, where they perform in front of celebrity judge Lindsay Lohan (guest-starring as herself). Meanwhile, Mercedes (Amber Riley) becomes ill and everyone begins to wonder how they will ever get to Nationals.
