The movie is about the work of Max Gerson and how it's helping people today, it's very well filmed, and the frame before the credit really underlines the message, that medicine is treating the symptoms, not curing, and big pharma will do anything they can to stop that.
Posters Note:
I've been trying to find info about this kind of stuff forever, and couldn't, until a very, very brief mention of this movie on the Alex Jones show.
