A special forces team nicknamed the "Iron Shadow Team" was accidentally involved in a major foreign-related terrorist incident during an ordinary training, ranging from border anti-drugs to desert tracking, deep-sea infiltration, and even urban counter-terrorism. The team members showed their true colors in the numerous tests of life and death and the spy network: there was conflict and more tacit understanding, and there was sacrifice and more humor. There are huge secrets hidden behind every crisis, and Lin Chen suspects that there is a black hand behind the "Iron Shadow" plan. The three volumes tell the story of the formation of the team, defeating enemy organizations in major incidents, and revealing the inside story of the "Iron Shadow" plan. The team members retired, were promoted, or changed jobs. The story ended with a sad and happy farewell, showing passion, growth, and team bonds.
