Ambitious businesswoman Angela Marks finds herself navigating the complexities of both her professional and personal life. Working tirelessly for a cosmetics company, she manages to balance her career while being married to Curtis Marks, a cutthroat divorce attorney. The couple often spends time with their close friends, Sylvia and Danny Chambers, who are parents to two children and are stuck in a difficult marriage. It doesn’t go unnoticed by Angela how Sylvia struggles under the weight of their children’s demands, parallel to how Curtis deals with his law partner Danny’s apparent infidelity with other women.
In her quest to spearhead a major advertising campaign for a new perfume aimed at expectant mothers, Angela experiences an embarrassing mishap during her initial pitch to her intimidating boss, Mary. After an uncontrollable bout of flatulence clears the conference room, Angela manages to salvage the moment, receiving the green light to develop a proposal for the fragrance that could potentially earn her a vice-presidency position.
Their relationships are put to the test when the two couples gather for dinner. While the Marks are eager to share their achievements—Angela excited about the perfume account and Curtis boasting about a high-profile divorce case—they soon witness the unmistakable tension between Sylvia and Danny, leading to an abrupt end to the evening.
As the night progresses, Sylvia confronts a shocking reality when she catches Danny in a compromising situation. Enraged, she kicks him out, prompting her to seek comfort from Angela. However, Angela’s own life takes an unexpected turn when she visits her friend and doctor following bouts of nausea—only to discover she is pregnant, despite their attempts at safe practices.
This unplanned pregnancy shatters Angela’s world, plunging her into despair. Walking home in a haze and protesting to bystanders, “I’M NOT PREGNANT!”, she witnesses a disturbing scene at a restaurant where Curtis awkwardly fends off the advances of his overly flirtatious client, Mrs. Jenkins. Misunderstanding what she sees, Angela confronts Curtis when he arrives home, accusing him of infidelity. When he expresses confusion over her accusations, realizing she hasn’t grasped the full story, he is perplexed. The news of her pregnancy brings him joy, but it also intensifies Angela’s sense of betrayal as she mutters, “the father isn’t who I thought he was.”
These tensions escalate during a drinks meeting with Danny, where Curtis shares his concerns over Angela’s alleged cheating, pointing out the implausibility of her being pregnant if they were taking precautions. This leads Curtis to decide to seek refuge at Danny’s place, leaving a despondent Angela behind, enveloped in her unrest, as both of them spiral deeper into accusations of unfaithfulness.
The emotional riff only widens, exacerbated by interference from their respective families and friends. As Curtis finds unexpected entertainment when arriving at Danny’s home, things get chaotic. Meanwhile, at Sylvia’s, Angela is advised to force Curtis’s confession and subsequently remove him from her life. Yet, neither of them seems to regard the truth of their love for one another.
Desperately trying to avoid confrontation, the Marks agree to limit communication, which leads to an unbearably tense nine-month period. Despite landing the lucrative perfume ad campaign, which she keeps hidden from her demanding boss, the weight of Angela’s pregnancy becomes unbearable.
As the day of the CEO pitch for the perfume approaches, Marie rushes into the office demanding a last-minute pitch preparation. In the midst of this chaos, Sylvia hands Danny divorce papers, unaware that Curtis is also on a frantic mission.
When the moment arrives and all characters converge, Angela unexpectedly goes into labor while pitching to investors. In a twist of fate, the misunderstandings dissolve during Angela’s crucial moment. Soon, as if by magic, the Marks find their way back to each other, emerging from the tumultuous experiences as proud parents to a beautiful baby boy. The journey of misunderstandings transforms into a heartwarming resolution, affirming their love amidst the chaos of life’s unpredictabilities.
