From a North Korean football team that mysteriously vanished to an American defector who spent most of his life in the DPRK, three newly available documentaries seek answers to some of the country’s most stubborn enigmas while shining a light on the private lives of citizens in the totalitarian state. 

“The Game of Their Lives,” “A State of Mind” and “Crossing the Line” from director Daniel Gordon and producer Nick Bonner together form an informal trilogy that offers compelling insights into these and other historical episodes from North Korea.
