Hyun Soon Jik is ninety-six years old. She is the oldest living resident in Jeju Island. She lives in a small village in Seogwipo-si. A natural diver with good sterminates, she became a high rank Haenyeo at an early age and has led an astonishing career of diving for eighty-seven years. Though she looks more comfortable when she is under water than when she is at home, she quit diving in October,2020, and goes to sea every day, missing her old life as a diver. When she does, Chae Ji Ae (39) who has been disciplined by Hyun, accompanies her and looks after her. Together they head for Deulmoolyeo, a place that only Hyun can find, to see the water flowers that bloom under water.
