Jiang Zhaoyue returns from an enemy prison camp expecting a medal, but instead faces accusations of treason. To prove her innocence, she sneaks back across the snow line alone and wipes out an enemy forward camp in a single night. Yet intelligence major He Wenzhou personally sends her to the interrogation room. Tang Li finds a discrepancy in the casualty records, and Xu Jingshu deciphers a deadly message. Only then does Jiang Zhaoyue realize that behind the prisoner-of-war scandal lies a covert network that has infiltrated the war zone for years. She must reclaim the honor of her uniform and learn anew, amid the artillery fire, to trust in love and her comrades.
