Lin Youyou has always felt she should have been a security guard, not a police officer. Just after she submits her resignation, a case leaves her deeply questioning both her past life and herself.

A woman in a green dress jumps to her death in the spring rain at night. Her father turns up in a freezer, while her mother falls silent... One case after another points to the woman who jumped to her death. But why does it seem that the hand guiding everything behind the scenes is connected to the case involving Lin Youyou's father fifteen years ago? Who is leading them down this path?
