Eddie Cantrow, Ben Stiller in the lead role, runs a small but bustling San Francisco sports shop and lives life with a carefree single mindset. His world begins to tilt at a wedding where he confronts the reality of being the only one at the reception still waiting for “the one.” Sitting at the “singles table”—a cluster that ironically looks more like a rowdy kid party—he watches as others toast with a mix of hope and humor, a moment that foreshadows the comic embarrassment and awkward honesty to come.
A tense, almost comic misunderstanding during a purse snatching leads to a fateful, chance encounter with Lila, the woman who will reappear in his life in surprising ways. After a brief, cordial exchange where she seems to be toying with fate, Lila reappears at Eddie’s shop, and their next meeting becomes a spark that neither of them anticipated. What begins as light banter quickly deepens into dating, and Eddie finds himself drawn to her, even as he senses a few troubling signals.
Lila drops a major emotional bomb when she reveals she works as an environmental researcher and might have to move to Rotterdam for work. Yet the job realities complicate more than they clarify, because the company isn’t known for sending married employees abroad. Against the advice of his father Doc and his loyal friend Mac, Eddie makes a impulsive life choice and marries Lila after dating for less than two months, hoping for something genuine to cling to in a world that feels unsettled.
The road to their honeymoon in Los Cabos, Mexico becomes a road trip of revelations. Eddie discovers quirks in Lila that annoy him—she sings constantly, a habit he can hardly ignore on a long drive. Their bond experiences a rough first test during an intimate moment on the way, revealing that Lila is passionate and aggressive in bed, a contrast to what Eddie expected. He tries to see past these traits, hoping love might grow, but more things come to light that shake his judgment.
Lila’s past adds another layer to his misgivings: a disclosure of substance use and a deviated septum that occasionally causes awkward nose-related mishaps in social settings. She also shares that her involvement in environmental work has been more volunteer-based than financially stable, and that the “thief” Eddie heard about is tied to an ex who owed money. Eddie starts to realize he may have mistaken the person he chose to marry, recognizing that he isn’t in love with her and is increasingly unsettled by her habits and the reality of their relationship.
The honeymoon stretches into a comedy of errors. On a sunlit beach, Lila insists on using baby oil and rejects sunblock, despite Eddie’s cautions about sun exposure. A second-degree sunburn becomes the least of their problems when Eddie meets Miranda, a vacationing woman from Mississippi whose family takes a shine to him. The majority of Eddie’s time on the trip shifts away from Lila, as he finds himself drawn into Miranda’s world and her family, while Lila remains mostly confined to their hotel room.
Miranda’s relatives welcome him with warmth, except for her cousin Martin, who harbors skepticism about Eddie from the start. Misunderstandings escalate as the family misreads Eddie’s intent—rumors swirl that he has come to Mexico to mourn a wife who was lost to a violent act. The tension peaks when Eddie contemplates divorce during a casual lunch, only to be confronted by Martin and Buzz, who escalate the confrontation in a way that tests Eddie’s patience and resolve. A chaotic scene involving a pepper and a nose—along with a jellyfish sting—becomes a memorable, if uncomfortable, turning point in Eddie’s life on the trip.
Lila’s response to this crisis is surreal and comic: she tends to Eddie’s stings by urinating on him, a spectacle witnessed by many, underscoring how far their marriage has strayed from affection and trust. In the end, both Lila and Miranda leave Eddie—Miranda for his lies and Lila for his desire to end the marriage. To complicate matters further, Lila destroys Eddie’s passport, stranding him on a Mexican beach.
Dejection drives Eddie toward heavy drinking, and he finds himself entangled in a new plan to set things right with Miranda. Under the influence and with a push from a local hotel owner named Uncle Tito, a friend of Mac’s, Eddie heads to Mississippi to make amends. The border crossing becomes a comic chase as border patrols repeatedly intercept his attempts to reenter the United States, yet he finally makes it to Oxford, Mississippi.
There, Eddie discovers Miranda has married someone else. He decides to honor her happiness and leaves, but not before a tense, emotionally charged moment where Miranda’s husband is confronted, and Doc intervenes. Eddie agrees to back off if Miranda truly loves her new husband, and she confirms that she does. He departs with Doc, unaware that Miranda still harbors feelings for him.
Eighteen months pass, and Eddie’s life has taken another turn: he’s divorced from Lila, who has taken control of his store, and he now lives a nomadic beach life in Mexico, selling sporting goods to travelers with little stability. Then Miranda appears again, having left her husband and still carrying a flame for Eddie. The reunion is warm, hopeful, and full of possibility—yet the final twist reveals a lingering complication: Eddie has remarried someone named Consuela, which sets him on a fresh, at times hopeful, at times ironic, loop of misadventure. In the end, the story stays true to its core: a man learns hard lessons about love, timing, and the quirks that define human connection, all filtered through a comic lens that leaves him wiser, if not entirely cured of his romantic optimism.
