Joint Security Area
From the DMZ separating North and South Korea, two North Korean soldiers have been killed, supposedly by one South Korean soldier. However, the 11 bullets found in the bodies, as well as the 5 remaining bullets number to 16 bullets, at the assassin's magazine clip. The exploring Swiss/Swedish team by the countries suspects that the other was included - each one of which points into a sort of cover up. The truth is significantly simpler and more awful.
