Zhou Muye, the youngest special operations captain of the Dragon Kingdom, once swore an oath to protect his family and country. However, during a joint border exercise, he led his team into an enemy trap and was wiped out. The truth gradually emerged - not that intelligence was leaked, but that someone deliberately betrayed it. After returning to China, Zhou Muye discovered that his fiancée had become the wife of an enemy agent, and that agent was his former brother in life and death.
