In a struggling 1998 coastal village, debt-ridden fisherman Thomas and his compassionate wife Mary pull a mysterious little girl, Lulu, from churning typhoon waves. Treating the stranded orphan as their own beloved child, they welcome her into their drafty seaside shack. The impoverished couple soon discovers young Lulu carries an astonishing ability to communicate with ocean currents and locate valuable marine shoals.
Guided by Lulu's instinctive nautical directions, Thomas lands record-breaking hauls of rare yellow croakers, lifting his household out of grinding poverty. However, their sudden prosperity attracts the jealousy of corrupt harbor bosses and ruthless lenders determined to exploit the child's miraculous gift. Thomas and Mary fiercely protect their lucky daughter, proving familial devotion outweighs any earthly fortune.
