The story revolves around the 'Ultimate Iron Eagles'. They shoulder the mission of carrying out difficult, transnational counter-terrorism and rescue missions, and each team member becomes a best friend because of their unique experiences. In an environment full of crisis and tension, the team members worked together with humor and mutual trust to overcome obstacles, from running in to tacit understanding, and then to working side by side in life and death. They were brave and fearless in the face of the enemy, continued to grow and break through themselves in the team, and finally completed their missions, and each gained a transformation in their lives. The three major stages of tasks are interlocking, gradually revealing the larger behind-the-scenes mastermind and international conspiracy. The plot is compact and ups and downs, and the humor style runs throughout.
