Plot
Professional bull rider Luke Collins meets Sophia Danko, an art student at Wake Forest University, after she attends a PBR event. On the way home from their first date, they spot a car crash in the woods and help rescue an elderly man from the vehicle, along with a box full of letters.
In the hospital, Sophia visits the 91-year old man she rescued, Ira Levinson. He explains the letters are what he wrote as a teen to his late wife, Ruth, and she offers to read them to him, which tell the story of how they met and fell in love in 1940.
In flashbacks, Ruth tells a young Ira that she wants a big family, and he eventually proposes to her before leaving to fight in World War II. However, Ira is shot during an attack and is later informed that he can no longer have children, news that causes distance between Ruth and Ira when he returns. Regardless, they decide to make it work and move in together, decorating the house with many paintings that Ruth and he love.
Back in the present day, Ira is moved to a nursing home where Sophia continues to visit. Luke continues bull riding as Sophia and he fall in love. He attends an art exhibit with her, which he finds uninteresting, and they realize how different their two worlds are; Luke says he does not feel their relationship will work.
Sophia goes to Ira for advice, who tells her how he and Ruth made it work. In flashbacks, it is revealed that Ruth, a school teacher, became attached to a young student named Daniel McDonald after finding out she and Ira wouldn't have children of their own. They wanted to adopt him but Daniel's uncaring relatives wouldn't allow it.
Luke is injured while riding and is rushed to hospital. He is advised not to ride again but he refuses to accept that his career is over. Following an argument, Luke and Sophia break up. In flashbacks, Ira and Ruth break up because she cannot see a life without children in their future. However, weeks later, Ruth returns as she cannot live without Ira. Decades later, now 80 years old, Ira wakes up to find Ruth has died in her sleep.
One night, a woman knocks on his door, claiming to be the wife of Daniel McDonald, the child they almost adopted when they were younger, and informs Ira that Daniel, who later became a professor of physics and astronomy, has died. She gives him a portrait of Ruth that he had painted, with a message on the back that reads: "Ruth Levinson, third grade teacher. She told me I could be anything I wanted to be when I grew up".
Sophia and Luke are contacted by Ira's attorney who tells them that he has died and an auction will be held for his collection of paintings. Meanwhile, Luke wins his last ride, and the event championship, but feels disappointed because Sophia is not there to share it with him.
Going to the auction, Luke buys the first piece of art, a simple painting by Daniel "Portrait of Ruth". He and Sophia reconcile with a kiss after he tells her he will not ride anymore because what he really wants is to be with her for the rest of his life. The auctioneer then reveals Ira's clause in the auction rules was: whoever buys Daniel's portrait will receive the entire collection, worth almost $200 million, as it is the piece of art that meant the most to him.
A year later, Luke and Sophia, now married, have built an art gallery dedicated to Ira and Ruth and their paintings. He takes her to Black Mountain College where Ira and Ruth used to spend their wedding anniversary. They sit under the same tree and read Ira's letters together.
