- The special operations team lost contact while performing a cross-border reconnaissance mission. Lu Chuan was ordered to lead the reconnaissance company to the site of the incident - the primitive jungle of "Death Valley" for search and rescue. On the way, they found the bodies of the special forces members. The circumstances of death were bizarre. The scene was full of strange features, such as no obvious signs of fighting, inexplicable tears on the bodies and wounds caused by suspected biological and chemical weapons. At the same time, Lu Chuan discovered that the symbols on the cloth in the deceased's hand were related to the border smuggling case half a year ago, and realized that the matter was not simple.
