How often can a person start over? A wealthy suburb of Stockholm in the 1960s: Laurits loves playing with his best friend, swimming and diving at the summer house, and especially the piano lessons with Miss Andersson. He feels more comfortable everywhere than in the presence of his high-strung mother and his domineering father, who envisions a future as a doctor for his son. But when Laurits turns 18, a career as a concert pianist is within reach, and he plays for his life. Then everything turns out differently than expected; Laurits finds his calling as a doctor—and with his great love Silja and their daughter Liis, he finds happiness. Until years later, at a family celebration, he learns that his life is built on sand. He makes a fateful decision... "The Reason" tells the story of a man who is repeatedly forced to reorient himself.
