The Legend of the Blue Sea

In 1958, the nobleman Dam-Ryung releases a mermaid back into the ocean. In present-day Seoul, the figure of conman Joon-Jae stands on the same spot.

Joon-Jae brings a beautiful woman back to his hotel, unaware that she's a mermaid. Jin-Ok realizes she's been scammed and sends men after Joon-Jae.

With no memory, Joon-Jae finds himself alone on a beach next to a jade bracelet and a single pearl. Meanwhile, the mermaid crosses the ocean to Seoul.

At the aquarium, Joon-Jae runs into a woman being chased by security. Feeling a sense of déjà vu, Joon-Jae rescues her and brings her home.

Joon-Jae lives with the woman who he names Sim Chung. Fugitive Dae-Young has been on the run for 3 months when a murder occurs near Joon-Jae's house.

Sim Chung is involved in a traffic accident. Joon-Jae rushes to the hospital to find her in critical condition.

Joon-Jae tells Sim Chung he loves her. Meanwhile, detective Hong comes across Dae-Young while investigating a murder.

Jung-Hoon teaches Sim Chung that jealousy is the way to a man's heart. Meanwhile, Joon-Jae sees an image of a man with a mermaid on an ancient vase.

Joon-Jae finally faces off with his pursuer Dae-Young. He suffers a major injury and confesses his feelings to Sim Chung before losing consciousness.

In a museum, Joon-Jae sees a figure in a painting that looks just like him. Unable to identify the figure as Dam-Ryung, he grows distraught.

Sim Chung leaves the house after learning Joon-Jae is a conman. In a panic, Joon-Jae desperately searches for her.

Joon-Jae is arrested by detective Hong. When Sim Chung realizes they are in danger, she tracks them down.
