Based on the celebrated novel by Emily M. Danforth, The Miseducation of Cameron Post follows Cameron (ChloA Grace Moretz) as she is sent to a gay conversion therapy center after getting caught with another girl in the back seat of a car on prom night. Run by the strict and severe Dr. Lydia Marsh (Jennifer Ehle) and her brother, Reverend Rick (John Gallagher Jr.)--himself an example of how those in the program can be 'cured'--the center is built upon repenting for 'same sex attraction.' In the face of intolerance and denial, Cameron meets a group of fellow sinners including the amputee stoner Jane (Sasha Lane), and her friend, the Lakota Two-Spirit, Adam (Forrest Goodluck). Together, this group of teenagers form an unlikely family as they fight to survive.
