At 19 years old, Loren Schauers made a choice most of us will never have to face. This week, Andrea and Crystal cover the story of a young man whose ordinary workday on a bridge construction site turned into a fight to survive an accident that should have killed him instantly.

Ep. 43: Bad Medicine

At a crowded state institution on Staten Island, hepatitis wasn't just common. It was almost guaranteed. Instead of treating it, one doctor decided to use it.

Ep. 42: It's a Cult of Personality

"Two Women Sue Church When Christ Fails to Appear" In a small Utah town, a self-proclaimed prophet convinced dozens of followers that the Second Coming had a date on the calendar. When it didn't happen the way he said, he didn't lose his followers. He just adjusted the story. This week, Crystal and Andrea head to Manti, Utah, to unpack the rise of a charismatic leader who claimed direct communication with God, built a following through seances and secret plural marriages, and somehow talked his
