The life of Walter (Richard Jenkins Richard Jenkins) remains the same. He has taught the same course for more than 20 years, co-authored books he has never contributed to, and asked private tutors to learn the piano and it is difficult to get along with others. Life is like a pool of stagnant water. His life didn't change until shelly, who co-authored the book with him, was due to give birth and was unable to attend the annual academic meeting instead of Walter. Walter, who seldom went to New York because of his wife's death, was surprised to find two strangers when he returned to his home in New York. After a misunderstanding, I realized that the young couple had been deceived into renting the room. Walter asked them to stay. Tarek is a passionate young man from Syria who loves to play drums, and his girlfriend is a black man from Senegal. Walter was moved by Tarek's cheerfulness, learned to play drums with him and followed him to the park to participate in minority drumming exercises. On this day, Walter and Tarek hurried home after practice. Tarek missed the best chance to pass the checkpoint while crossing the subway. He was arrested and detained by the police when he skipped the checkpoint. Walter, this.
