Shen Zhiyi, the adopted daughter of an aerospace family, discovers that her soon-to-be sister-in-law Lin Wanqing is a foreign spy. She exposes her in public but is accused of leaking the secret. In order to protect national secrets, she and her "brother" Shen Linchuan pretended to break up, but in fact they joined forces to set up a trap.
