In bustling New York in the 1980s, the world of puppeteer Vincent (Benedict Cumberbatch) completely collapsed the moment his son Edgar disappeared. He was immersed in endless despair and self-blame, and he struggled to find the home where he once laughed and laughed every day. Eric, the blue monster puppet drawn by his son Edgar, became the only comfort in Vincent's heart. He firmly believed that as long as Eric could appear on the TV screen, the missing son who had brought him endless joy would return to him. However, in pursuing this belief, Vincent's crazy behavior gradually cost him family, colleagues, and even detectives who had tried to lend a helping hand. In the endless loneliness and darkness, Eric became Vincent's only ally, accompanying him on the long journey to find his son. This is a journey full of love and despair. People can't help but be moved by Vincent's persistence and pray for the little figure who has never returned.
