With the arrival of a new competitor and Chairman Cheon wavering, Gwanseok scrambles for a solution.

Gwanseok and Heedong are offered a job salvaging treasure off the coast of Korea and head to Mokpo.

Gwanseok and Heedong's gang hunts for the exact location of the sunken treasure.

After seeing the pottery, Jungsook is convinced of its value, and the gang makes their first dive.

Sensing trouble, Gwanseok rushes to Muan. After Professor Kim’s boat sinks, Gwanseok, Heedong, Jungsook and others fight over the remaining treasure.

Professor Kim flees to Busan with the loot, with Honggi in pursuit. In Seoul, Gwanseok takes on a task. Heedong and Seonja reach warehouse in Muan.

The team get their first taste of success, and Gwanseok accepts a secret task from Chairman Cheon.

Gwanseok and Heedong eventually agree to team up with Professor Kim on the salvage operation.

Heedong's turn to dive arrives right after an unexpected accident occurs.

With a barge and villagers recruited, the salvage operation takes an unexpected turn.

The sunken ship finally emerges before Heedong's eyes.
