In 2017, Kim Jong-un’s half-brother, Kim Jong-nam, was ambushed in a Malaysian airport by two women bearing a lethal chemical weapon 10 times more powerful than sarin. He died en route to the hospital. Who planned the murder of Kim Jong-un’s half-brother, and what does it reveal about the leader and his regime?

Frontline: North Korea’s Deadly Dictator is now available on DVD. The program is also available for digital download.

As nuclear tensions between President Donald Trump and North Korean leader Kim Jong-un escalate, producer Jane McMullen examines claims the North Korean leader and his intelligence services ordered the assassination on Kim Jong-nam, and sheds light on his broader intentions and nuclear capabilities.

Drawing on interviews with a leading North Korean defector, diplomats, experts, Kim Jong-nam’s school friends and even a former North Korean secret agent, the documentary is a rare glimpse inside the secretive country; an eye-opening look at both how King Jong-un thinks, and how he’s trying to ensure his regime’s survival and perpetuate his own power.
