"Devil's Playground" follows several teens through their experiences during rumspringa, but the main focus is on Faron, the son of an Amish preacher. When he is exposed to the world "outside," he becomes addicted to crank, or crystal meth. He ends up dealing to support his habit, and hooks up with an "English" girlfriend. He acknowledges that he will probably have to say good by to her when he rejoins his community, which from the beginning of his Rumspringa never seems to be in doubt. Faron frequently says that he believes in the Amish church, it's a good religion, and makes two attempts to get off the drugs, knowing he must if he is going to return "home."
In interviews with the teenagers, the documentary shows that partying is never all that is on their minds. These young Amish adults are struggling with what they want to believe, how they want to spend the rest of their lives. The downside to putting off baptism in the Amish church until you are old enough to choose is the tragedy that occurs if you die before you choose the church, because the Amish belief system affirms that anyone not baptized is lost. The Amish teens seem to take this very seriously.
