Cen Huan (Zhu Xu Dan) is part of the Hua Xin Shi sect that helps people shed unhealthy thoughts and worries that keep them from happiness, then collects their newly pure desires to do greater good. Cen Huan meets a doctor (Dylan Xiang) who impresses her with his good works, so she joins him and his assistant (Li Jun Chen) in their journeys to help the people who need them most. They gain two more altruistic members along their way (Bao Tian Qi and Sun Bo Hao). Cen Huan learns that the Hua Xin Shi has an evil counterpart, the Yang Xin Shi sect that uses people's worst thoughts to grow evil in the world. Despite the danger, her group of five decide to do whatever they can to stop the Yang Xin Shi and save the world.
