The story revolves around the life of General Sima Yi of Cao Wei. Despite possessing great wisdom, Sima Yi (Wu Xio Bo) used to be a cowardly bookworm who shied from dangerous situations. However, his life changes after a meeting with Cao Cao (Yu He Wei) who became intrigued by what lies behind Sima Yi's fierce and agitating stare. Sima Yi was forced to become an official serving the Cao Family and ultimately forges an alliance with Cao Pi (Li Chen) to help him become Cao Cao's heir. Sima Yi was an indispensable asset during the war due to his talent as a military strategist. While Cao Cao acknowledges Sima Yi's capabilities, he also views it as a threat. In order to survive, Sima Yi feigns weakness and insanity, even going as far as to fake his own death as he waits, for that opportune moment to rise up once and for all.
