Five years ago, while working as a security guard in a high-end residential complex, Arthur (Art) Miller unintentionally caused the death of Carol Miller's abusive husband and Mark Peterson's father while trying to save the constantly abused mother and daughter. At the time, his daughter Lily Miller had just been admitted to university, and Arthur (Art) Miller reluctantly handed over her university fees before going to prison. Five years later, Arthur (Art) Miller was released from prison and visited his daughter with gifts, full of expectation, but was treated coldly by his daughter and even kicked out of the house. It turned out that Lily Miller had suffered discrimination because of her father's imprisonment, and she hid the truth about her father in order to maintain a stable life in her in-laws' house. Faced with the world's indifference and prejudice, Arthur (Art) Miller chose to be tolerant of his daughter. In the end, father and daughter broke the shackles of the world and reconciled.
