A Naija Christmas unfolds the poignant journey of a devoted mother, whose heart aches as her sons remain stubbornly unmarried, leaving her longing for grandchildren. In an effort to inspire change and stir action among her children, she boldly challenges them, declaring that the first-born son to marry will inherit her beloved home in Ikoyi. This provocative challenge sets the stage for a comedic yet heartfelt series of events.
The story takes a lively turn when Ajike, a talented musician, is in the studio recording when her romantic interest, Ugo, enters with a date. Furtively, she hides, becoming an unintended spectator to Ugo’s charm as he flirts with his companion. However, chaos ensues when a group of scorned women storms into the studio, furious over Ugo's infidelities. The turmoil crescendos outside where Ugo is dismayed to discover that his car has been vandalized. Meanwhile, Mama hosts a gathering with the members of the Ladies of Undiluted Destiny, only to be ridiculed for her lack of grandchildren.
Amidst this familial turmoil, Obi’s public proposal to Vera is met with mixed emotions as she walks away, causing Mama to faint upon witnessing the event via livestream, pushing her into the hospital. There, she expresses her frustration to her sons: they must get married, and the first to do so will claim her property. Complicating matters further, the scheming Tony Torpedo, a notorious loan shark, confronts Ugo to demand repayment for his debts. Desperate to find a partner, Ugo's attempts to reconnect with past flames yield no results.
In the midst of this chaos, Obi tracks down Vera in her workplace and implores her to help him win her heart back by delivering an impressive pitch. Mama, always optimistic, takes her sons on a quest to church, hoping to find suitable wives. During this excursion, Ugo encounters Ajike, a dedicated chorister, and offers her a free recording session in an attempt to impress her. As he strives to win her affection, Ugo steps up to play the drums at the church, showcasing his commitment.
As the Ladies of Destiny prepare for their Christmas gala in Mushin, Mama is unfortunately unable to attend due to her hospitalization. Concurrently, Obi presents a brilliant idea to a cable company revolving around the ghetto gala, which they enthusiastically accept. In a twist of fate, Vera invites him to a romantic dinner, while Ugo and Ajike bond over her demo recording in the studio.
However, the story takes a darker turn when it’s revealed that Ugo’s furniture is disappearing amidst the chaos. Chike, one of the other brothers, finds himself entangled with one of the mothers, Sammy, leading to a tangled web of relationships that culminates in comical misadventures. Ugo's misfortune continues as he finds himself beaten and comforted by Ajike, prompting him to ask her out on a genuine date.
Yet, in this world of burgeoning romance, complex emotions churn. Obi struggles with his feelings as he juggles his affection for Vera against the backdrop of his tumultuous connection with Kaneng, who tries to stir jealousy by claiming to be back with an ex-boyfriend. Their tumultuous dynamics reach a boiling point during a party, culminating in Obi rejecting Vera’s proposal, instead opting for a kiss with Kaneng.
Ugo finally goes on a real date with Ajike, and as their relationship develops, he learns that intimacy before marriage is discouraged by the church. The stakes heighten for Obi as he confronts the implications of his entanglement with Kaneng, bringing him face-to-face with Tony Torpedo, who decides to collect on some debts owed, including those concerning Ugo.
Confronted by the reality of their living situations, Ugo’s brothers express surprise over his missing belongings, leading to a dramatic confrontation regarding Ajike and her past relationship with Tony. Tensions simmer until Tony returns Ugo’s possessions, clearing the air.
As the festive spirit commences, Kaneng and Obi reconcile, with Obi secretly settling his debts with Tony. Finally, he introduces Kaneng to Mama at the Christmas party, where she receives her approval. In a heartwarming conclusion, Ugo is taken by surprise by Ajike at the party, allowing them both to mend their relationship amidst the holiday cheer, embodying the themes of family, love, and redemption entwined within A Naija Christmas.
