What's up for "Glee" season 4?
The video gives a hint to the drama that follows New Directions' national championship win:
Rachel (Michele), no longer a big fish in a small pond, clashes with the nasty dance teacher (Hudson) at her performing arts college, and William McKinley High School's star glee club has to find a way to stay on top.
Watch the show when it returns Sept. 13. Until then, check out the promo here:
