Desperate boatman Lin Feng, in order to raise medical fees for the daughter left behind by his sacrificed brother, takes on a million-dollar mission: within three days, cross the Death Sea to deliver pharmaceutical heiress Shen Qingxue and stepmom Lan Xin to Haichend. As soon as Shen Qingxue gets on the boat, she despises Lin Feng as a stinking fisherman, complaining about the broken boat and the dirty life jacket. But after going out to sea, the Sea Wolf Gang pursues them all the way. Lin Feng navigates dark water routes, sees through fake maritime affairs, and continuously counterattacks using fishing nets, reefs, and storm tides. Shen Qingxue changes from looking down on him to being conquered, gradually discovering that this cold, tough boatman is not greedy for money, but is paying off debts and protecting lives for his dead brother.
