Glee's Darren Criss introduces season 5 trailer: video
This is the first glimpse of the show since Cory Monteith's tragic death in July following a heroin and alcohol overdose.
There is no clue as to how Cory will be written out of the show, and his girlfriend Lea Michele only features in the clip for a brief second.
Darren tells viewers about the show's opening two-part special, which will focus on The Beatles. He also revealed that Sue Sylvester has been made principle of the school.
He says: "Sue Sylvester is up to her old tricks being evil and mean. Five seasons later Sue continues to destroy the Glee club."
