The film begins with Guillermo “Billy” Herrera (Andy Garcia) sharing his journey of escaping Cuba in search of a better life in America. Along the way, he encountered Ingrid (Gloria Estefan), and their whirlwind romance led to a beautiful marriage blessed with two daughters: Sofia (Adria Arjona) and Cora (Isabela Merced). Now, as the owner of a thriving architectural firm in Miami, Billy works diligently to ensure his family never faces the hardships he endured. However, despite his efforts, he finds himself grappling with a new, pressing dilemma.
As a couple, Billy and Ingrid are now undergoing therapy sessions with Dr. Saeger (Matt Walsh). While Billy genuinely wants to mend the fraying threads of their marriage, Ingrid feels utterly defeated and leans towards divorce, labeling her husband as a focused, stubborn workaholic who seems incapable of change.
As the family prepares for Sofia’s return from her job in Mexico, they are joined by Chi Chi, Ingrid's mother ([Marta Velasco]), Junior, Billy’s brother ([Enrique Murciano]), and Tio Walter ([Ruben Rabasa]). Meanwhile, Cora has dreams of working as a professional designer but faces rejection when her unique quinceañera dress design fails to impress a customer, leading her to resign from her position at the dress shop and return home frustrated.
Upon Sofia’s arrival, a family dinner becomes the perfect setting for an important announcement. Just as Billy and Ingrid plan to share their divorce intentions, Sofia surprises everyone with her engagement to her coworker Adan Castillo ([Diego Boneta]). While the family rallies in support, Billy's disapproval is evident, as he insists they shouldn't proceed with marriage without first meeting Adan. This strife leads him to escape to his friends for a game of dominoes, where Sofia ultimately finds him. After triumphing in a match, she persuades him to return home with her, where he reluctantly attempts to show his support.
Adan soon pays a visit to meet Sofia's parents, and while Ingrid takes an immediate liking to him, Billy remains aloof. Ultimately, however, Billy manages to grant Adan his blessing for marriage, only to discover that Sofia and Adan plan to wed within just weeks and intend to move to Mexico afterward. This revelation deepens Billy's concern, leading to a tense night on the couch when Ingrid expresses her frustration over Billy's pessimism.
Subsequent family interactions robustly contrast Billy's conservative values with the modern ideas brought forth by Natalie Vance ([Chloe Fineman]) and her assistant Kyler ([Casey Thomas Brown]), the wedding planner for Sofia and Adan's big day. Despite the couple's wishes for an intimate ceremony, Billy is determined to host the wedding at one of his architectural triumphs, leading to tension between father and daughter.
During a dress-fitting outing, Sofia recruits Cora to create bespoke designs for the wedding after she expresses dissatisfaction with the store's selections. Initially hesitant, Cora embraces the challenge as she receives encouragement from her sister. Meanwhile, Adan's ostentatious family, led by his wealthy father Hernan ([Pedro Damian]), proposes lavish expansions to the wedding plans, which irks Billy who wants to control the costs.
A lavish party on a yacht sets the stage for clashes between Billy and Hernan, culminating in heated disagreements over wedding arrangements. Billy's frustrations boil over as Hernan insists on using his own luxurious venue, prompting Sofia to assert that she will marry Adan regardless of her father's involvement.
Billy attempts to reconcile with Sofia while she tries on her wedding dress; however, tensions flare when the truth about his impending divorce spills out at an engagement party, igniting anger and disbelief among the family members.
As a storm rages outside, Cora, feeling the emotional weight of family turmoil, retreats to her parents' bed, reuniting the sisters for solace in childhood memories. When they arrive at the wedding venue, disaster strikes as the storm has wreaked havoc, closing access to the location. Amid the chaos and the heartbreak of possibly canceling the wedding, Natalie organizes a hasty ceremony back at the Herrera home.
The family bands together to create an impromptu wedding scene, where Cora's custom dress shines as Sofia and Adan exchange vows in a meaningful ceremony belayed by love, creativity, and adaptability. Billy, recognizing the importance of family, offers to assist Cora in launching her own dressmaking business, while the sentimentality surrounding the day culminates as Sofia plays her parents' wedding song, inviting Billy and Ingrid to share a moment on the dance floor.
By the end, amidst their shared experiences, Billy proposes a trip to Greece as a farewell to their marriage, suggesting they “go out with a bang.” With a newfound sense of hope and intimacy, Ingrid agrees, closing the chapter on their tumultuous relationship with a kiss that suggests the flicker of romance may still endure.
