Lou Mazzuchelli, an uninspired English teacher at Stanton High, petitions to take over as director of the school's theater program in an attempt to revitalize his passion for teaching, but quickly realizes he has his work cut out for him. His controversial decision to change the musical to the more provocative Spring Awakening and his atypical casting choices create a ripple effect for the program's assistant director Tracey Wolfe, the school's football coach Sam Strickland, and the students in the show.

Lou is brought down to earth when his production budget is slashed, Coach Strickland vindictively monopolizes Robbie's time, and he has a conflict with Tracey. Lilette finds herself starting to fall for Robbie, while Simon contends with conflicting feelings about his role in the show. As Michael finds support within the theater troupe, Gwen acts out in rehearsals in response to tensions at home.

Gordy agrees to volunteer in the theater, bringing him back onto Gwen's radar, while his family tries to come to terms with Maashous' imminent departure. As Robbie faces the severity of his mother's illness for the first time, Lilette waits for her mother to return home. Tracey and Lou work to prepare "Spring Awakening" for opening night, but can't see eye-to-eye on how to address notes from the administration.

SEASON FINALE. During opening night of "Spring Awakening" personal crises and dilemmas percolate in the wings backstage as Simon struggles to overcome his biggest fear, Lilette withholds a huge development from Robbie, Robbie has a momentous breakthrough, and Tracey draws a line in the sand. Over the course of one evening, decisions are made that will change Lou and Stanton Drama forever.
