Trina is excited to plan her husband Liam’s birthday, but he tells her he has to go away for work. Soon after, Trina discovers that Liam’s best friend, Mandy, is having an affair with him. Hurt and betrayed, Trina decides to get her own revenge.
Trina never doubted her marriage, but everything changed when Liam’s birthday approached. He claimed a work trip and promised to celebrate later, but Trina felt uneasy when he kept mentioning their “lifestyle” and how work was essential for it.
The next day, while out with her mother, Trina spots Liam and Mandy together in a restaurant, kissing. Shocked, Trina realizes Liam lied and was spending his birthday with his mistress.
Her mother devises a plan: Trina pretends to be pregnant and invites Mandy and Steve to dinner. At the dinner, Trina announces the “pregnancy” and claims the baby is Steve’s, revealing that she knew about the affair. The shocking confrontation sends Mandy running to the bathroom, where her affair with Liam is exposed.
Liam and Mandy’s secrets unravel. Trina calmly tells Liam there’s no baby and that she set up the whole scene to see his reaction. With evidence from nanny cams and Steve as a witness, Trina is prepared for a smooth divorce. Her prenup ensures Liam will get nothing, and Steve has the upper hand in his marriage to Mandy.
Though devastated, Trina feels a sense of justice and relief.
