On Christmas Eve, a former police officer and single father to a daughter was murdered. The suspect was arrested, and the case seemed to be over. However, the case begins to move again with a letter left by the deceased former police officer to his daughter. In it, he wrote, "If the people listed below are arrested and indicted... they are falsely accused." That list included the name of the person arrested for killing her father. The daughter, believing her father's letter, decides to unveil the mystery behind her father's death, despite the possibility that the dark secret her loving father hides from her might come to light.
