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.

Robbie's two worlds collide at a house party where his football teammates face off with the drama troupe; Tracey reluctantly explores a new relationship with a not-so-secret admirer; a family road trip to visit Gail's sister goes sideways.

After their unresolved confrontation with Gordy, Lou and Gail try desperately to get through to him. Lou discovers a crucial element to the show needs a major overhaul, while Tracey resists a blossoming romance. As Gwen reels in the aftermath of a shocking announcement from her parents, Simon finds an unlikely ally. Robbie and Lilette grow closer just as outside forces conspire to put them at odds, and Vanessa takes a stand.

As Lou's vision for "Spring Awakening" starts to crumble, Lilette and Robbie feel the weight of responsibility on their shoulders with rehearsals going into overdrive. In reaching out to a student in need of support, Tracey opens up old wounds from her own past. Gwen starts down a destructive path that threatens to disrupt Gordy's attempts at self-control, while Simon takes steps to get closer to Anabelle.

Tech week at Stanton High finds Tracey and Lou leading the cast through a series of rehearsals that falls short of expectations. Gwen's familial strife leads to a wild night out, while Michael tries to reconnect with an estranged friend. Maashous receives potentially life-changing news, and Simon's personal feelings start to compromise his performance in the musical.

When an unauthorized, provocative sizzle reel promoting the Stanton High production of "Spring Awakening" is posted online, it spreads like wildfire through the school and surrounding community. Coach Strickland and Vanessa are forced to face their daughters, but major damage has already been done. Robbie faces a crisis of confidence, while Maashous contemplates a difficult family reunion.

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.
