Devil's Playground (2002)
Devil's Playground is a 2002 documentary film by Stick Figure Productions, directed by Lucy Walker about the experiences of several Amish youths deciding whether to remain in or leave their community and faith during the period known as rumspringa ("running around" in Pennsylvania Dutch). The film follows a few Amish teenagers in LaGrange County, Indiana who enter the "English" (non-Amish) world and experience partying, drinking, illegal drugs, and pre-marital sex. Some teens in the film profess that they will eventually become baptised as adults in the Amish community. If they are baptized, then leave the church, they will be shunned by family and friends; one girl recounts her experience of this.
