In the early 1970s, a marriage alliance between military families from the northern and southern commands runs into trouble. Jiang Yanting, a sharp-tongued and highly skilled military doctor from Nancheng, is transferred north. Lu Chenzhou, the cold and aloof young master of the Lu family, refuses the match, but is forced into marriage anyway. Bound by a written contract, they become husband and wife in name only. She faces hostility at the hospital, while he uses his authority to keep powerful officials in check. From disaster relief and rescue missions to political maneuvering, sparks fly as their opposing wills stir hidden currents. Their sham marriage gradually turns into something real, as they test each other and move carefully, one step at a time. Whoever falls first loses the game.
