“Glee” follows 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. His wife, whose acquisitiveness is out of control, wants him to ignore his love of teaching and quit to become an accountant, so they’ll have more money for her to spend.
