It reminds me of the movie Pleasantville, where two teens are transported to a black and white conformist 1950's world. As one tries to blend in, another rebels, and the more rules are broken the more colorful it becomes.
I would caption it as:
Shunned and humiliated by the Jehovah's Witnesses for being raped, a courageous young woman sadly realizes she has been part of a destructive cult and lied to and deceived her entire life. As she attends the Kingdom Hall for the last time, she looks back and feels sad for the still deluded cult members. She will miss her former friends, but looks forward to being able to get an education and attain her dream of becoming a doctor, something she couldn't do as one of Jehovah's Witnesses.
