South Korea has some of the fastest internet in the world, and this film looks at what that speed has cost. Dr. Lee Jae-Won describes gamers playing for four or five days without stopping, arriving at hospital with slipped discs and blood clots from sitting motionless for so long. Dozens of killings have been linked to online gaming addiction, and the film cites cases of infants left to die while parents played uninterrupted. Psychiatric units treating the addiction describe caseloads they cannot keep up with. The film then turns north, to the cyber warfare unit North Korea has built to strike its neighbor's networks. Former unit member Jange Se-Yul explains how the regime recruits its most capable programmers and trains them as, in his words, soldiers of a cyber terror war. Kim Hung-Kwang, who helped design the program before defecting, describes attacks already carried out on a South Korean bank and an attempted intrusion at Incheon International Airport, and warns that a serious strike could cut power and water rather than just data.
