ELI5: Explain Like I'm 5

Lost boys (Mormon fundamentalism)

The Lost Boys are young men who have grown up in Mormon Fundamentalism, which is a set of beliefs that are more strict than mainstream Mormonism. They were forced to leave their families and communities when they were adolescents because the leaders of their communities said that the boys were not following their beliefs. These boys faced very difficult lives, as they had to find a new place to live and provide for themselves without the support of their families and communities.
