As Nino approaches his significant 33rd birthday, he shocks his family by announcing his upcoming wedding, set to take place in just three weeks. This shocking news sends waves of confusion and concern throughout the household, especially among his three sisters: Sonja (who is married to Hugo and juggling her artistic ambitions), Michelle (dedicated to her charity work and her husband Jan), and Wanda (a free-spirited creative involved in a secret affair with Hugo). The sisters are left reeling from Nino's decision, primarily because he has been living with Felix, making his choice to marry Bo, a woman he barely knows, perplexing.
As the sisters congregate at the registrar's office to confront Nino, they are startled by Bo's warm and friendly nature, which only adds to their confusion. Initially, the sisters conspire to thwart Nino's wedding plans, but their attempts ultimately prove futile. Meanwhile, Sonja finds evidence of Hugo's affair with Wanda, compelling her to take a creative form of revenge by incorporating a narrative about their secret romance into her latest piece.
With the wedding date approaching, Bo becomes unknowingly caught up in the sisters' schemes, as she remains blissfully unaware of their underlying motives. Ultimately, Nino's truth surfaces when his sexuality is revealed, yet Bo surprises everyone with her acceptance and understanding of his relationship with Felix. However, her unexpected announcement that she is pregnant with Nino's child sends his life spiraling out of control, forcing him to grapple with his doubts and evolving understanding of his gender identity.
On the wedding day, Nino’s mother steps in and invites Felix to participate in the ceremony, prompting Nino to cancel the event. In a moment of honesty, he confesses his true feelings to Bo, who provides constant support and encourages him to reconnect with Felix. In a remarkable twist, the registrar conducts the marriage between Nino and Felix on that very day.
In the aftermath, Nino begins a transformative journey, opting for gender confirmation surgery, while Bo gives birth to their child. As the family comes together at the hospital, Felix lovingly places their newborn in Nino’s arms, signifying a fresh start for this unconventional trio.
