About Schmidt

Warren Schmidt is retiring from his position as an actuary with Woodmen of the World, an insurance company in Omaha, Nebraska. After a retirement dinner, Schmidt finds it hard to adjust to his new life, feeling useless. He sees a television advertisement about a foster program for African children, Plan USA, and decides to sponsor a child. He soon receives an information package with a photo of his foster child, a small Tanzanian boy named Ndugu Umbo, to whom he relates his life in a series of candid, rambling letters.
Schmidt visits his young successor to offer his help, but the offer is politely declined. As he leaves the building, Schmidt sees the contents and files of his office, the sum of his entire career, set out for garbage collectors.
He describes to Ndugu his longtime alienation from Helen, his wife, who suddenly dies from a blood clot in her brain just after their purchase of a Winnebago Adventurer motor home. Jeannie, his only daughter, and her fiancÃ© Randall Hertzel arrive from Denver. They console him at the funeral, but Jeannie later berates him for taking his wife for granted, such as by refusing to fully pay for the Winnebago (he wanted the cheaper Minnie Winnie) and burying her in a cheap casket. He asks her to move back to take care of him, but she refuses. Meanwhile, Randall tries to entice him into a pyramid scheme.
Schmidt feels his daughter could do better than Randall, a waterbed salesman. After the couple leaves, Schmidt is overcome by loneliness. He stops showering, sleeps in front of the television, and goes shopping with a coat over pajamas to load up on frozen foods. In his wife's closet he discovers some hidden love letters disclosing her long-ago affair with Ray, a mutual friend, whom Schmidt angrily confronts.
He decides to take a journey alone in his new Winnebago to visit his daughter and convince her not to marry Randall. He tells Jeannie he's leaving early for the wedding, but she makes it clear she doesn't want him there until right before the ceremony. Schmidt decides to visit places from his past, including his college campus and fraternity at University of Kansas and his hometown in Nebraska. His childhood home has been replaced by a tire shop. While at a trailer campground, he is invited to dinner by a friendly and sympathetic couple. When the man leaves to buy some beer, Schmidt makes a pass at the wife, and flees in terror when she adamantly rejects his advance.
Sitting on the roof of his RV on a starry night, Schmidt forgives his departed wife for her affair and apologizes to her for his own failings as a husband. At that moment, he is amazed to see a bright meteor streak across the sky as a possible sign from Helen that she forgives him.
Feeling full of purpose and energetic renewal, Schmidt arrives in Denver, where he stays at the home of Roberta, Randall's mother. He is appalled by Randall's eccentric, socially odd family and tries unsuccessfully to dissuade Jeannie from the marriage. Schmidt throws out his back after sleeping on Randall's waterbed, infuriating Jeannie. Roberta assures Schmidt that a soak in her hot tub will help his back, but he flees after a nude Roberta makes a pass at him in the tub. The next day, Schmidt, under the influence of Percodan to soothe his back pain, attends the wedding and delivers a kind speech at the reception, hiding his disapproval.
On his way home from Denver, Schmidt composes a letter to Ndugu. Schmidt questions what he has accomplished in life, lamenting that he will soon be dead, that his life has made no difference to anyone, and that eventually it will be as if he has never existed at all.
A pile of mail is waiting for him at home. Schmidt opens a letter from Tanzania. It is from a nun, who writes that Ndugu is illiterate and doesn't know English but appreciates Schmidt's letters and financial support very much. A crayon drawing by Ndugu is enclosed, showing two smiling stick figures, one large and one small, holding hands on a sunny day. Schmidt is moved to tears as the film ends.
