Shi Guangrong, a 28-year-old social worker, is cowardly, stingy, and loves to take advantage of others. Possessed by "Old Zhou", a businessman who died more than 20 years ago, Shi Guangrong has been in a state of chaos ever since. Under the guidance of Lao Zhou, Shi Guangrong (forced) became a new generation of "big brother" and subdued the ghost brothers of Lao Zhou one by one. Each ghost brother is possessed/symbiotic with an ordinary person and has his own identity in the world.
