There are two ways to sum up this documentary. One will make you decide against watching it. Here’s that pitch: This is the story of a homeless woman who was found dead.

Here’s the better pitch: That woman was highly educated and generally lived a happy life. But she also left behind a detailed journal that recounts her final days in one of the coldest winters on record. She lived on apples and rainwater and fought off insanity.

Her heartbreaking story is one of disappointment and betrayal by society at a time when she was most vulnerable. A haunting and compelling documentary that is sure to stay with you for a long time and, in a way, might help you take on adversity.
