The members of New Directions are back in action and take on their biggest assignment yet: the Beatles! As Will enlists the kids to pay homage to the classic song catalog from the Fab Four, Blaine and Kurt attempt to answer questions about their future together. Meanwhile, Rachel's New York ambitions take an unexpected turn.

The glee club learns the dance of the hour: twerking. Meanwhile, Marley discovers Jake's relationship with Bree, and Rachel tries to convince Kurt they both should get tattoos.

Blaine believes he has the best plan to win nationals, but the other club members think he's too controlling; members of Kurt's band disagree over the venue of their first gig; Sue gets in touch with her feminine side.

After Rachel's humiliating failure as TV actress, she comes home to Lima to figure out what she wants to do next. Upon discovering that Sue has banished the arts at McKinley, Rachel takes it upon herself to reinstate and lead the Glee Club. Meanwhile, Blaine, no longer in a relationship with Kurt, has moved home to coach the Warblers while Will is coaching rival Vocal Adrenaline, and Sam is the assistant coach for the McKinley football team.

The members of New Directions must come together to prepare for their first public performance at a high-strung tween's bar mitzvah.

Dalton Academy burns to the ground, and the Warblers must combine with the New Directions to form a super group. Meanwhile, Rachel begs Carmen Tibideaux to let her return to NYADA.

All of Will’s hard work and dedication to the Glee Club and to fostering the talents and dreams of his students pays off in a major way, and everyone shares in the feeling of joy that permeates the school as teachers and students reflect on their shared journey. Old rifts and wounds are healed and new sights are set on a promising future. Everyone seems to be ending up exactly as expected and right where they belong… along with more than a few unexpected surprises.
