Five years ago, the heroine Shen Qingci broke up with her lover Gu Yubai due to a conspiracy and misunderstanding, and went overseas to become a war reporter. After her father (a former senior engineer in the military region) died unjustly, she returned to China as a special intelligence analyst for the military, vowing to find out the truth. They reunited with Gu Yubai, who was already the technical backbone of the military region, and the two were forced to cooperate in investigating the same transnational military espionage case and military industry corruption case. Old relationships are rekindled in crisis, and family ties (with stepmother and half-sister) are revived in confrontation. The villain (Gu Yubai's rival and extremely power-hungry consultant) will do whatever it takes to get the upper hand, obstructing him at all levels. In the end, the two teamed up to uncover the huge network of internal and external collusion, washed away their grievances, re-married amidst the flames of war and faith, and jointly protected their homeland.
