Mackenzie lives and breathes volleyball, but after coming out, she finds her passion for playing is challenged by the homophobic behavior of her teammates.

With the help of her friends, she sets out to establish a queer-positive league instead. The league will celebrate diversity and be somewhere LGBTQ2S+ kids can feel at home. When the school resists their efforts and then insists on a cringey name for the team--the Gay Alliance Club-- the friends, with the help of a sympathetic teacher, establish the league in their own space and on their own terms, learning a lot about empowerment, activism, and community in the process. Along the way, Mackenzie catches the attention of her crush, Brooklyn, and romance ensues, complicating and further enriching her life.
