MasterBuilder: REBUILT tells the story of a brilliantly accomplished, but self-annihilating architect who is building his dream home in order to help he and his wife overcome the tragic deaths of their twin baby boys twelve years earlier. When a mysterious girl from his past shows up and stakes a claim for him to build her the "castle in the air" that he had promised, matters at home grow increasingly onerous and volatile. Amidst the chaos and completion of the new home, and only seconds before his life will end, he discovers the key to pure love and happiness.
