After fisherwoman Yungu adopts Beibei, the family's destiny is completely rewritten by this pair of divine ears. Beibei is naturally able to hear the heartbeat of the seabed and discern treasures beneath the silt. In the poor yet warm Lin family, she relies on listening to sounds to point the way, leading her adoptive father Lin Haisheng, adoptive mother Yungu, and brother to dig out top-grade big crabs and find deep-sea large yellow croaker schools, not only curing her adoptive father's injured leg, but also turning the potless poor fishing family into the darling little wealth god of ten miles and eight villages.
