The three sisters of Laisheng run a coffee shop called "Cat's Eye". In fact, the three sisters are the daughters of Heinz, a great painter and collector, who mysteriously disappeared when the three sisters were young. With the disappearance of their father, all the collections in the house also evaporated overnight. So, the three sisters are lively and lovely girls during the day, and turn into thieves in the dark at night - "Cat's Eye Sisters". They only steal those collections that once belonged to their father, hoping to find clues about their missing father. The second sister, Laisheng Tong, is even more special because her boyfriend is the young policeman who is going to arrest the "Cat's Eye Sisters". Truth and love, the three sisters wandering in the dark look for answers to these questions in one crime after another.
