A mysterious, vengeful stranger rides into town and creates all sorts of havoc. It seems there are a number of people on his list and before he metes out justice to each one, he places a cross with that person's name on it in the middle of the street. The burning question becomes whether these people are dealing with a one-man army of flesh and blood or an avenging angel of death. The answer may lie in the betrayal and massacre of a Confederate Army unit during the Civil War...

Aspiring architect Tom Hansen works as a writer at a greeting card company in Los Angeles. He meets Summer Finn, his boss Vance's new assistant. They bond over their similar musical tastes, and at a company-sponsored karaoke night, they discuss love, which he believes in, unlike her, as her own parents had divorced. Tom's friend and co-worker drunkenly reveals that Tom likes Summer, which both assert is merely a close friendship. A few days later, Summer spontaneously kisses Tom in the office; Tom agrees to a casual relationship, and that night, they have sex. Over the first few months of their relationship, they grow closer. Tom accompanies Summer to a park bench in the city, his favorite location. Eventually, Tom's friends and work colleagues as well as his adolescent half-sister Rachel urge him to ask Summer about their relationship status, but Summer insists it is unimportant as long as both parties are satisfied. One night, Tom brawls with a man who attempts to make sexual and romantic advances toward Summer in a bar. After an argument, they reconcile and Summer concedes that Tom deserves some certainty but cannot promise to always feel affection for him. Slowly, their relationship becomes less passionate and they begin to continuously argue. After Summer quits her job at the greeting card company and ends things with Tom, citing their unhappiness, Vance transfers him to the consolations department, as his depression is making him unsuitable for happier events. A blind date with a woman named Alison fails, as Tom spends it complaining about Summer. Months later, Tom is invited to attend the marriage of a work colleague named Millie and attempts to avoid Summer on the train heading to the occasion, but she notices him and invites him for coffee. At the ceremony, Summer catches the bouquet thrown by Millie, and dances with Tom at the wedding reception. After she invites him to a party at her apartment, he arrives, hoping to rekindle their romance, but notices her wearing an engagement ring and tearfully departs. Sinking further into depression, Tom secludes himself in his apartment, only emerging for alcohol and junk food. After a few days, he returns to work heavily inebriated and emotionally quits his job on the spot. Rachel criticizes Tom's attitude, explaining that Summer was the wrong woman for him and that his depression stems from focusing solely on happy instances in the relationship. Tom finally reflects on the incompatibilities he'd overlooked. One day, he energetically rededicates himself to architecture, as Summer had encouraged him to do. He assembles a portfolio and secures job interviews. Tom and Summer re-encounter each other at the park bench. She has recently married, and he admits his inability to comprehend it as she never wanted to be serious with anyone. She explains that when she met her now-husband, she was sure of him in a way she wasn't about Tom. When he acknowledges his shortcomings about believing in true love, she reassures him that his beliefs are justified, but stresses their own romantic incompatibility. He wishes her happiness as she departs. On Wednesday, May 23, Tom encounters a young woman who is interviewing for the same position at an architectural firm as him, and they connect over his favorite location. He invites her for coffee once both of them are finished with the interview. She declines, but then changes her mind, revealing that her name is Autumn.

The film is presented in a series of vignettes, with narration provided by the adult Ralphie Parker. As a 9-year-old boy living in Northwest Indiana around the late 1930s or early 1940s, all Ralphie wants for Christmas is a Red Ryder Carbine Action 200-shot Range Model air rifle. Ralphie's request is rebuffed by his mother, then by his teacher Miss Shields when he writes about it in an assigned theme, and even by a disgruntled Santa at Higbee's department store, all of whom tell Ralphie "You'll shoot your eye out". On Christmas morning, Ralphie receives some presents that he enjoys, but is disappointed not to find the rifle among them. Ralphie's father ("The Old Man") directs him to one last box hidden in the corner, which proves to contain the rifle. Ralphie eagerly hurries outside to try it out, but when he shoots at the metal target he has set up, the BB ricochets and knocks off his glasses. Ralphie accidentally steps on and breaks the glasses while trying to find them; he makes up a cover story about an icicle falling from the roof of the garage and hitting his eye, which fools his mother and keeps him from getting into trouble. That night, Ralphie goes to sleep with the gun by his side, as his adult self reflects that it was the best Christmas present he had ever received or would ever receive.
