The series main focus is a treasure map that was inherited by Su Zhenyuan from his late father. That same map is also coveted by Lu Rongguang, who was Zhenyuan's business partner.
Meanwhile, Chen Shuxian and Chen Shufen came to Singapore for career opportunities, but their mother, who came with the sisters, was murdered shortly after arrival. Through the subsequent investigation, Shuxian got to know police officer Lu Zhiwei, and Shufen began an intimate relationship with Zhenyuan's son, Alex Su.
Shuxian, meanwhile, discovered that her mother's death may be linked to Zhenyuan, and later became embroiled on Rongguang's plot to get the treasure map.
