Ma Dongshan, Han Dechang and Song Tianming, three brothers, founded the "Hausen Hotel" and became the golden combination of the industry at that time. Thirty years later, the situation of these three brothers is not optimistic. Ma Dongshan is seriously ill and will not live long, Han Dechang passed away very early, and Song Tianming's beloved son is still missing. Ma Keai (played by Zheng He Huizi) is the daughter of Ma Dongshan, and Ma Dongshan decided to leave the entire family business to her. However, just when Ma Keai wanted to return to China, she encountered an incredible traffic accident. At the same time, she was told that her father had a heart attack and died. Ma Keai, whose life has changed dramatically, vaguely feels that things are not as simple as they seem, so she pretends to be ignorant and goes with the flow, and secretly begins to investigate the truth of the incident.
