Plot summary

First Sergeant Jack Falen comes home from Vietnam assigned to escort a friend's body across the country by train for a hometown burial. As he boards, a radio broadcast carries word that America and North Vietnam have signed a peace treaty. Jack expects a band and a parade to meet the coffin at the funeral. On the journey he meets Mark and two college students, Stephanie and Chloe, and he is drawn to Stephanie. He also spends time with Gene, a land salesman, and Emile, who talks about yoga positions. Jack cannot stay seated through a conversation, and his memories of combat keep intruding on the trip.
