The Net movie plot

A North Korean fisherman was fishing in a river on the north-south line when his boat's engine broke down and drifted downstream to South Korea. South Korean intelligence agencies took him away and interrogated him. Although they found that he had been a soldier, they could not find any evidence that he was a spy. The furious interrogator wanted to subvert the attack, frame the blame or even turn the tables, and indeed succeeded in tricking him into helping the North Korean spy pass on information. But the fishermen who would rather die than return to their North Korean families escaped and returned to North Korea thanks to various rescues and rescues by the security guards. But I never imagined that this fisherman, who the South Korean intelligence agency had nothing to do with him, would be abused by North Korean intelligence agencies after returning to North Korea. He was forced to write about his experiences in South Korea countless times. Disobedient and continued to fish, he was eventually shot in the river on the north-south line.
