Jong-chan (Kim Joo-hyuk) and his wife Yeon-hong (Sun Ye-jin) have been married for many years and have a lovely daughter. They are both talented and beautiful, and in the eyes of outsiders, they are like a couple of gods. Jong-chan has entered politics and has made some achievements in his career. His colleagues all know that he will most likely become the next member of Congress. One day, bad luck befell this happy family. The daughter disappeared for no reason, leaving behind vague clues that are difficult to explain, leaving the police clueless. What makes Yeon-hong feel incredible is that Jong-chan doesn't seem to be so anxious about his daughter's disappearance. All he thinks about is how to win the next election, and the relationship between the couple has cracked. In desperation, Yeon-hong had to cheer up. She knew that her daughter could only rely on herself.
