Xu Zhi, the chief forecaster of the Municipal Meteorological Bureau, and Ling Chao, the captain of the Municipal Emergency Management Bureau, unexpectedly met due to a sudden typhoon "Langmao". When they first met, the two had a dispute over the accuracy of weather data. However, in the process of dealing with typhoons and rescuing a missing fishing boat, they gradually let go of their barriers and discovered that they shared a common commitment to the city's safety and reverence for life.
The shadow of the old case of Typhoon Haiyan three years ago made Ling Chao have a grudge against weather forecasting, and also made Xu Zhi bear inexplicable self-blame. As the typhoon season comes again and again, from the Qingwan Town dam rescue to the treatment of hidden dangers in old ships, from the heart-warming promise of the first snowy sunrise to the warm companionship of the New Year in the fishing village, the two not only find out the truth about the old case of "Haiyan" and clear Xu Zhi's grievances, but also let a tacit understanding that begins with responsibility slowly sublimate into a deep love.
Together they predicted the path of the typhoon, strengthened the fishing port dams, protected the coastal villagers, and collected warmth in their ordinary lives together - the fish soup noodles in the old neighborhood, the hot pot in the first snow on the top of the mountain, the seafood porridge of the grandmother in Qingwan Town, and the shell bracelets in the children's hands have all become precious marks in their love. In the end, the two settled down on the seaside of Qingwan Town and had a lovely daughter. They spent their lives fulfilling the promise of "staying together through thick and thin and staying with each other year after year", letting the original intention of guardianship and the warmth of love be like a lighthouse on the seaside, forever illuminating every day and night in this city.
