Highland War

In 1952, during the Panmunjom negotiations, the ownership of L Highland directly affected the delineation of the ceasefire line. In order to obtain more favorable results, the North and the South launched a new round of bloody competition around L Highland. At this time, the captain of the Korean Crocodile Squadron on the front line was killed by his own pistol. At the same time, letters from the families of the Northern People's Army soldiers were secretly sent through the Korean mail route. The Korean side suspected that there was a traitor on the highland front line and sent Lieutenant Jiang Enbiao (played by Shin Ha-kyun) of the investigation department to accompany the new captain to the Crocodile Squadron. At this time, the Crocodile Squadron is actually controlled by Jiang Enbiao's former comrades, Lieutenant Kim Soo Hyuk (played by Gao Xiu) and Captain Shin Rirong. Jiang Enbiao is surprised to find that the once bookish Kim Soo Hyuk has now become a powerful warrior, and the Crocodile Squadron, which appears to have loose military discipline, has amazing combat effectiveness in actual combat. Jiang Enbiao went through a tug-of-war for the highlands with the Crocodile Squadron, and he finally stumbled upon clues to the Crocodile Squadron's "collaboration with the enemy"...
