Liberty in North Korea (LiNK) has been one of my favorite non-profits for over 5 years now. They are a team dedicated to helping North Koreans get out of their country, while also supplying them with tools like education to help them adapt to life outside the DPRK.
LiNK has made quite a few films to shed more light on what is happening in North Korea, and just released a new award winning documentary called I Am Sun Mu.
Sun Mu was once an artist in North Korea, in charge of creating propoganda for the regime. After escaping, he uses his art in a completely different way.
You can watch it on Netflix or any of the sites listed here
