Three-year-old Lila Shaw can understand the language of seawater and marine life. She is sent by a sea turtle to fisherman Chad Shaw, and calling him Daddy Chad brings light to the family that was about to sell their boat. Lila helps Chad find tidal channels, gain abundant harvests from tide foraging. From repairing the broken boat to leasing salt fields and developing aquaculture, she leads the whole village to turn the abandoned beach into a thriving wetland. Facing external development, Chad and the villagers choose to guard the sea they share. It is a warm story about family, the sea and protection, featuring a cute little girl tide foraging and a loving father-daughter pair working together.
