Lance Valenteen, portrayed by David Boreanaz, is a cunning man who expertly manipulates the emotions of three women, ultimately leading them back to their former partners. His approach varies with each woman: with the first, he flaunts an exaggerated machismo; with the second, he brings about public embarrassment; and with the last, he invokes sheer terror through a harrowing hang-gliding experience.
Bill Smith, played by Pat Healy, steps into Lance's innovative "Mr. Fix It" shop, ostensibly looking for computer help but soon realizes he's being scrutinized to confirm whether he's genuinely heartbroken. Lance then reveals a video that outlines his calculated method to win back clients' ex-girlfriends. He leverages details from the women's exes, gains their trust, and then poses as the perfect boyfriend, only to drive them back to their previous relationships by outdoing their former partners in bad behavior. He also ensures his clients that they'll get a complete refund if he fails, and no sexual involvement is promised, which is alluring to many.
Feeling lost after Sophia, portrayed by Alana de la Garza, ends things with him, Bill spends extra money on Lance's services. Meanwhile, Lance fantasizes about transforming his Camaro into a stunning race car and ultimately achieves his goal of becoming a professional racer after securing a victory in a local race.
Lance runs into Sophia, who is working as an exotic dancer, and finds himself irresistibly drawn to her. Eager to bump into her more frequently, he adopts a dog so they can meet at the park, where Sophia often walks her own. Their interactions unfold with Lance showcasing his talents, including a street performance that ends with an embarrassing mishap orchestrated by Sophia. The pursuit of love continues as Lance encounters neighborhood kids during go-kart races, where he skillfully counters their cheating tactics. However, his efforts are thwarted when Sophia playfully sabotages him.
Their relationship develops as they share dinner and dancing, where she expresses disdain for dishonesty stemming from her past with Bill. As the days pass, Lance reveals more about himself, including personal struggles and the loss of his father. Yet, Sophia often leaves abruptly, leaving him confused and questioning the very nature of love.
As Lance prepares for a significant racing event, he misinterprets Sophia's decision not to return to Italy as an opportunity to execute his heartbreak strategy. He discusses with Bill how to make Sophia believe he is a terrible person. Their plan is intricate: they will create the illusion of him being neglectful and deceptive, setting the stage for her to return to Bill.
In a twist of events, Lance learns of Bill's duplicity in orchestrating their emotional entanglement. When confronted, Bill reveals he initially hired Lance to ensure Sophia wouldn't accept his infidelity. The situation escalates as Lance chooses to confront Sophia, confessing his love for her just as she tries to leave.
Ultimately, a surprising twist unfolds. As Lance discards his "Mr. Fix It" image and confronts his feelings, he is met with applause from friends, realizing they had set up a scenario to encourage him to experience true love. After hearing that his misjudged endeavors have caused Sophia to leave, he flings her the keys to his treasured Camaro and closes the door on their tumultuous relationship.
However, as the narrative progresses, a glimmer of hope shines through. Sophia, actually named Karen, returns the Camaro to Lance and reveals her own love for him. No longer pursuing her deceptive business practices, she offers him a position as her race car driver, solidifying their budding romance with a passionate kiss just as he begins his race, propelling the story toward an exhilarating conclusion.
