On this week’s Glee season 4, episode 20, “Lights Out,” when the power goes out at McKinley High, Will and Finn enlist the members of New Directions to “unplug” and perform acoustic numbers. Meanwhile, Isabelle Wright (guest star Sarah Jessica Parker) asks Kurt to volunteer at the Vogue.com charity event, with Rachel and Santana in tow.
Glee is based on an optimistic high school teacher as he tries to transform the school’s once top-flight, but now moribund Glee Club and inspire a group of talented but unfocused performers to make it to, and win, the biggest competition of them all: Nationals. In his way is not just the indifferent principal, but also the sponsors of the cheerleading and football groups both of whom see his efforts as detracting from their own.
In addition to the regular cast, GLEE has featured guest appearances by a wide range of talented performers, including Gwyneth Paltrow, Carol Burnett, John Stamos, Britney Spears, Kristen Chenoweth, Idina Menzel, Jonathan Groff, Molly Shannon, Olivia Newton-John and Neil Patrick Harris, who won an Emmy for Outstanding Guest Actor in a Comedy Series for his work on the show.
