Under the bustling fabric of Shanghai, there is a century-old mysterious old house named "No. 1131 Huaihai Middle Road". It is not only the intersection of time and space, but also a hospital carrying endless joys and sorrows and the miracle of life.
Chen Mo, a real estate agent on the verge of despair, accidentally picked up a broken 1947 land deed on a rainy night, and has since been branded with the ancient "gatekeeper" mark. He met Zhang Wanqing, the cheongsam shop owner, the heir to the bungalow, a woman burdened with the family mission and the pain of time and space. They discovered that the red sand veins in this bungalow connected the tragedy of the plague in 1947, the medical accident in 2002 and the current medical crisis.
In order to save the sick children entangled in time and space diseases, they must work together to deal with five female allies with different identities and the covetous Lu Group. In the process, Chen Mo and Zhang Wanqing transcended the barriers of time and space, and their relationship became increasingly deep. They changed from tacit partners to lovers who depended on each other for life and death, and eventually became "twin night watchmen" to guard the passage of time and space together.
However, the price of protection is huge. With the pregnancy and birth of her daughter "Nian Nian", greater conspiracies and ancient curses emerged one after another. They must make a choice between love and sacrifice, the past and the future, use a deep love that transcends time and space to fulfill a century-old sycamore agreement, and compose a magnificent poem about life, healing and eternal protection.
