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.
