"Return of the dead + identity mystery + redemptive sadomasochism" in the context of the doomsday wasteland. Three years ago, Shen Jingzhe sacrificed his beloved Lin Qiuhe with his own hands to protect the base. Three years later, a person with all Lin Qiuhe's memories returned. Her appearance shook the wall that Shen Jingzhe had built with power and responsibility. But the question is - is this Lin Qiuhe really resurrected, or is it a psychological weapon planted by the enemy around her? If it was a lie, why did she even remember the late-night agreement that only the two of them knew about? If she is real, who was the person who was executed back then?
