The Day of Betrayal, I Took EverythingEpisode 9

Former beauty queen Wendy thought marrying into the Carter family was her fairy-tale ending, only to discover it was a living nightmare. Her husband Jonathan sees her only as his "No. 113 collectible" and is secretly having an affair with her sister-in-law, Chloe. Betrayed and belittled, Wendy refuses to suffer in silence. Armed with an IVF pregnancy and a strategically swapped piece of underwear, she ignites a path of calculated revenge. Teaming up with Sean, her husband's scorned illegitimate brother, she exposes Jonathan's litany of sins at the climax of the family's farewell banquet. Just when everyone believes she is only fighting for a divorce, Wendy reveals her true fangs—she demands not just her freedom, but for the entire Carter dynasty to pay for their arrogance.
