Current and past members of New Directions reunite for one final assignment - to reinvent their favorite performances. But these new versions of the series' most iconic tracks should not be seen as goodbye to glee club. On the contrary, they are celebrations of what the club has meant to each and every member.

Few months after the end of the glee club, New Directions alumni are adjusting to their new lives in the Big Apple: Blaine and Sam have moved in with Kurt, while Artie experiences difficulties navigating the mean streets of Manhattan. Also, Rachel gets accustomed to being a Broadway star, and Mercedes moves to New York to work on her album.
