Ka Chung (played by Carlos Chan), who comes from a broken family, and Pui Yi (played by Carol Chow), a single mother who is not appreciated for her talent in the performing arts, set up a company that can provide "rental family" services. By chance, Ka Chung discovered Zhiguang (played by Eric Tsang), a temporary actor who is obsessed with acting, and sincerely invited him to join the ranks of "rental family". Zhiguang readily agreed. After Zhiguang joined, he met Fangfang (played by Tien Niu), a landlady who likes dancing. By chance, the two of them played "temporary couples" and became "a family" with Ka Lok and Pui Yi. Who knew that this temporary family discovered a secret buried deep in the process of service... What exactly is a family? What is the most valuable relationship? Director Liu Weiheng allows the audience to reflect deeply through this story.
