Fu Yunshen, president of Xinglan Group, and his wife Jiang Ran arrive on a remote island. When he wakes up, however, he discovers that his wife has already sailed away. Stranded on the deserted island, he draws on his engineering expertise to repair a navigation beacon and is rescued eleven days later. By then, the group's personnel situation has changed, and the resort left behind by his father is facing an inspection crisis. With the help of Tang Ruoxi and Song Zheng, Fu Yunshen gradually uncovers suspicious equipment and financial dealings, protects his rights through legal means, insists that safety comes first, and pushes the project to undergo rectification. In the end, he stands by his principles, completes the resort's handover, and ensures that the island's light continues to guide people home.
