In the year 1971, former Korean Air Force fighter pilot Tae-In (Ha Jung-Woo) works as a pilot for a commercial airline. He faces a crisis inside a hijacked flight with the passengers, including Yong-Dae (Yeo Jin-Goo), and his crew members, including Captain Kyu-Sik (Sung Dong-Il) and Flight Attendant Ok-Soon (Chae Soo-Bin).

During the Japanese colonial era, roughly 400 Korean people, who were forced onto Battleship Island 'Hashima Island' to mine for coal, attempt to escape.

Hae-woong, an assembly member candidate, is taken out of the running because he became a thorn in the side of a local bigwig, Sun-tae. Hounded by loan sharks, due to defaulting a campaign loan, he decides to get his hands dirty. He steals classified government’s information about an urban development plan and obtains the help of a local gang leader, Pil-do, by promising hefty real estate profit. Now Hae-woong re-enters the race and tries to take revenge on Sun-tae. Unbeknownst to him, his messy journey through politics has only just begun.

A young woman named Yeon-hee is traveling to Pyongyang with a coach full of elderly people. As she flips through old photographs, she remembers telling her husband Min-woo that she wouldn't allow him to "cross over" to North Korea given the political situation of the day. But Min-woo left anyway and never returned home, and their marriage was torn apart by the Korean War. Now, sixty years after the division of Korea, she looks forward to reuniting with her beloved Min-woo again.

Children who live in hiding with superpowers, along with their parents who live with painful secrets of the past, face enormous dangers together.
