Jeju is an enviable island to everyone, but we cannot forget the deep pain that exists. Over half a century ago, tens of thousands were slaughtered under the specter of ideology; only a few years ago, in April, so many students were buried in our hearts without arriving on this beautiful island. Everglow begins with the cute struggle of Kyung Hoon, who visited Jeju to make a documentary about Jin Ok, a female diver. Kyung Hoons work becomes a sincere mission for the souls buried in the deep sea and mountains.
