When high school Spanish teacher Will Schuester (Matthew Morrison) becomes the director of the school's failing Glee club, New Directions, he hopes to be able to rejuvenate it. The club competes in the choir competition circuit. It's been called "a High School Musical for adults", the series follows the club and its mixture of oddball members as they try and restore it to its former glory. It is a musical comedy in which the eager and ambitious students not only compete to win the Nationals, but also have to deal with the tough and cruel realities of their school, McKinley High. At the same time, Will is trying to rejuvenate his failing love life while preventing the school's cheer leading coach Sue Sylvester (Jane Lynch) from sabotaging the choir.

"Tina in the Sky with Diamonds"

The second of two tribute episodes to the Beatles features the McKinley prom. When Tina is named one of the nominees for prom queen, she capitalizes on the potential votes of girls without dates for her campaign. Although she ends up winning, Tina's triumph is sabotaged by new cheerleader Bree, who drops a bucket of red slushie on Tina while she is on-stage. Roz informs Sue that Bree is behind the prank and demands that she is punished, but Sue instead promotes Bree to captain of the Cheerios, encouraging her to further torment the New Directions to toughen them up for Nationals. Rachel and Santana make a new friend at the diner where they work: a struggling artist named Dani. Dani is attracted to Santana, and the two share a kiss. Sam is attracted to the new school nurse, a college sophomore named Penny Owen. Mr. Campion, the Funny Girl director, informs Rachel that she has been cast as Fanny Brice.

"A Katy or a Gaga"

Kurt recruits Santana, Dani, and a reluctant Rachel to join his band, which she names "Pamela Lansbury". He holds auditions at NYADA, but the only applicant is Elliott, an overly bold performer who calls himself "Starchild". Kurt fears Starchild is too edgy, but ultimately reconsiders and invites Starchild to join the band. Will divides the glee club between those who identify with either Katy Perry or Lady Gaga, and instructs each group to perform a song from the other group to strengthen their weak points. Marley refuses to change for the assignment and joins the club's performance of "Applause" dressed as Katy Perry; Will suspends Marley for breaking the rules of the assignment. Jake is frustrated in his relationship with Marley, and he seduces Bree when Marley refuses to have sex with him. After being informed of Will's assignment, Sue suspends the glee club for a week for dressing inappropriately on school grounds.

"Puppet Master"

Kurt books the first formal performance for Pamela Lansbury, but the band disagrees over his choice of venue. Will instructs the New Directions to brainstorm ideas for Nationals. When the club reacts badly to Blaine's suggestions, Blaine refuses to perform and sits in the back of the choir room. A gas leak in the rehearsal room causes Blaine, Jake and Sue to hallucinate. Blaine later apologizes to the glee club for his behavior. After the superintendent mistakes her for a man, Sue confesses to Becky that she changed her feminine appearance when she started working at McKinley to gain respect from the students. Sue is promoted to full-time principal by the school board. Bree warns Jake that his narcissism and promiscuous ways will have unwanted consequences, and cuts ties with him due to his bad influence. Moved by her words, Jake tries to make amends with Marley, who confesses that she now only views him as a friend.

"Trio"

Rachel is revealed to have moved in with Elliott, who feels caught in the middle of her fight with Santana. Tired of the girls' feuding, Kurt reconvenes Elliott and Dani to form a new musical venture, One Three Hill. Santana and Rachel watch the trio perform, during which Santana points out that they share a hunger for success and a willingness to backstab others. Tina, Sam and Blaine sneak onto school property overnight to spend time together before their impending graduation, but Becky unexpectedly attaches herself to their group. Tina and Sam later sneak off to make out, acting on their unresolved sexual tension. Will and Emma become distracted from their teaching jobs when they decide to have a child, including having sex on school grounds during work hours. As Will packs for Nationals, Emma reveals that she won't be going, as she is pregnant.
