Zhou Mo, a bottom-level extra, was forced to "sign" with three late masters after being electrocuted - the "drama emperor" who pursues depth, the peerless actress who is obsessed with style, and the martial arts master who believes in boxing. He must deal with three pressures at the same time: making a living, avoiding an identity leak crisis caused by an accidental celebrity disguised as a woman, and reconciling the quarreling artistic obsessions of his three mentors. In the early days, he struggled to survive in the film and television industry by relying on the "cramming-style" teaching of the tutor group. He repeatedly overcame obstacles and was recognized for his acting skills. However, the secret of "women's clothing" was spied by the villain and repeatedly threatened. In the middle period, an identity crisis broke out in the public opinion. Zhou Mo reversed his reputation with hard power in the desperate situation. In order to completely break the situation, he devoted himself to a very challenging stage play and worked hard. In the later period, he returned as the king of artistic achievements, took the initiative to resolve his identity crisis, and integrated the obsessions of three mentors into a landmark work. In the end, he himself became a legend, completing the transformation from "puppet" to "master".
