In an abandoned resort on the South Korean island of Jeju, a group of people perform a symbolic funeral ritual to end a world built on hierarchies, division and destruction.

Hyun Soonjik is the oldest living resident in Jeju Island. A natural diver with good skills, 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 Jiae 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.

There are five grandmothers, four of whom went to Jeonju Prison due to the Jeju 4.3. All of them were young people around the age of 20 at the time of the incident in 1948. The outline of the incident is formed when hearing the experiences of those who were sent to prison without trial particularly as women. The audience feels indescribable emotions by the fact that they have lived on despite what they had gone through, things that are just too much for a human being to bear.

70 years ago, a massacre called ‘Red Hunt’ occurred in Jeju island. Over 6 years, countless lives were murdered in the Daranshi cave, Jungbang waterfall, and Ompang field. There was no line between life and death. There were only ideological and political strategies that surrounded Jeju. After 49 years, survivors can finally testify the memories that could not be forgotten.

A follow-up to 1996's documentary on the massacre at Cheju island, Red Hunt 2 exposes the real facts of the outrage upon personal rights and the brutal butchering occurred 50 years ago. Lives of nine survivors with their grieving testimony expose the horror of six yearlong massacres by Rhee Seung-man regime which still lingers today.

Immediately after liberation, an incident called 'Jeju Uprising' took place on Jeju Island, the Hawaii of Korea, under the control of the US military government. As a result, about one-tenth of the total population of the island at that time was sacrificed. The children who survived the massacre record the memories of that day in an animated film 70 years later.

Focusing on Mrs. Kang Sang-hee’s life, she lost her husband in the Jeju Uprising (March 3rd, 1948). The film views the dark-side of Jeju Island, a huge grave, which is completely opposite of the other side of the island, the famous tourist attraction. It says that the tragedy has been going on about the recent Gang-jeong village situation.

On the shores of Jeju Island, a fierce group of South Korean divers fight to save their vanishing culture from looming threats.

Following water's flow through the volcanic body of Jeju Island, the film traces resilience across geological, historical, and mythical time. A lone visitor enters a cave where submerged memories—of militarization and exploitation—surface through sound.
