18-year-old fishing village girl Lin Zhao was driven out of her home by her aunt, who only threw her a broken fishing net, while her younger sister Lin Kui suffered from pneumonia and coughed up blood but had no money for treatment. Late at night, she rowed a sampan and broke into the distant sea, discovering that her mother's fishing net came with a catching sea system that could continuously evolve with the catch amount, attracting fish schools and transforming into a light shield to resist winds and waves. From large yellow croakers to bluefin tuna, every net of hers was fully packed; she replaced it with a large boat and formed a fleet, becoming the youngest boat owner in the fishing village. Facing village bullies ramming boats and fishing bullies blocking her path, she solved every trick and spoke with her strength, also bringing the women in the village to go out to sea together and get rich. The end of the fishing lights is the way home; this time, the ones steering the helm are themselves.
