There is a hidden road in the forest. At the end of the road, there is a lake full of reeds. Below the lake is a fishing ground. There are boathouses and hotels on the lake. From a distance, it looks like one island after another.

The owner of the lake, Xizhen (Seo Jeong), is a beautiful Sargam. In the morning, she makes a living by sailing to pick up residents and selling fish food to fishermen. At night, she comforts men with charming body power and charming eyes. She drowned the guest who didn't know how to be gentle and did a lot of bad things in the lake when no one was around in the middle of the night, but saved the capable good man who tried to die many times.
