诸葛亮巧设奇谋，以智胜敌。他令姜维趁夜袭敌，率兵攻打天水城，并告知太守马真，自己已归顺蜀汉，劝其也一同投降。马真立刻命令士兵放箭，不许姜维活着离开。姜维无奈，只得退兵。
事实上，那个人是假扮姜维的替身，是诸葛亮与赵云设计的计谋。他们站在远处的山上观察，确认马真已中计后，便带兵转攻季城。
真姜维正镇守季城，忽见蜀军主力远去，仅余一队运送粮草的小兵，遂起夺粮之意，亲率兵马追击。不料赵云伏兵杀出，措手不及，只得退兵返城。待他撤回季城时，却发现城门早已为蜀军所据。姜维大惊失色，只得一路败逃，兵力尽失。
他孤身奔回天水，站在城高呼下请求开门。马真看到他，大骂其反复无常，再次命人放箭驱赶。姜维伤心地逃走，想到马真对自己的误解以及母亲在季城的安危，悲从中来，泪落满面。
