New York firefighter Patrick Sullivan (Jeffrey Dean Morgan) finds his seemingly perfect life turned upside down after receiving unintended guidance from the esteemed love guru, Dr. Emma Lloyd (Uma Thurman). Initially thrilled about his impending marriage to his fiancée, Sophia (Justina Machado), everything begins to unravel when Sophia seeks advice on a radio show hosted by Dr. Lloyd. During the broadcast, Dr. Lloyd challenges Sophia’s perception of love, ultimately prompting her to end their engagement, leaving Patrick heartbroken and bewildered.
In a bid to confront Dr. Lloyd, Patrick enlists the help of a tech-savvy neighbor to fabricate a marriage between them. This deception leads to a chaotic twist in Emma's life, as she discovers she can't marry her fiancé, Richard (Colin Firth), due to this fictitious marriage. Patrick’s persistence results in an unexpected attraction as he becomes increasingly entwined in Emma's life, leading her to juggle lies with her true feelings. Despite the allure of Patrick's charm, Emma wrestles with her growing feelings while striving to maintain her commitment to Richard.
As the plot thickens, Patrick finds clever ways to keep Emma close, such as stepping into Richard's shoes during various encounters, including a wedding cake tasting. Their dynamic takes a wild turn at a banquet where Patrick's charisma inadvertently secures Richard's business arrangement—despite Emma’s internal conflict over the complex web of deception they’ve spun. Amidst escalating drama, they bond during a culturally rich Hindu ceremony, where Emma witnesses a different, more vivid side of Patrick, igniting a flicker of attraction yet again.
The stakes rise when Patrick visits Emma at her radio studio, leading to a heated exchange that culminates in a steamy kiss inside a locked elevator, revealing the undeniable chemistry between them. Torn between Patrick and Richard, Emma must confront her feelings, ultimately leading her to call off her wedding. In a moment of passion and vulnerability, the two share a night together, but the following morning reveals Patrick's initial intentions to manipulate Emma, shattering her trust.
Despite their intense connection, both Patrick and Emma find themselves lonely as they try to navigate their separate paths. One fateful day, just before her wedding, Patrick makes a heartfelt confession of love over the radio, compelling Emma to reassess her choices. With her father's sage advice echoing in her mind, she arrives at the church where Richard selflessly encourages her to follow her heart.
In an elaborate turn of events marked by fire department chaos brought on by Emma's antics, she ultimately finds herself reunited with Patrick just in time to declare their love and start anew. The movie beautifully wraps up a year later, showcasing Emma’s pregnancy and the couple’s unwavering love, all set to the enchanting backdrop of the Tamil song "Swasame" from Thenali, cementing their happy ending.
