Kristi, a seasoned flight attendant, endures a humiliating encounter with a smug businessman and his glamorous companion during a flight. Hours later, she’s stunned to find the same man—Edwin—introduced as her mother’s new fiancé. Alarmed by his duplicity, Kristi warns her mother, but is dismissed as jealous and mistaken.
Determined to expose him, Kristi contacts the woman from the flight, Isabella, and together they orchestrate a sting. Disguised as a waitress, Kristi records Edwin soliciting money under false pretenses. She even swaps his phone, uncovering dozens of manipulative messages to other women.
Though Kristi’s actions lead to a restraining order and estrangement from her mother, she and Isabella rally the deceived women. On Edwin’s wedding day, they crash the ceremony, publicly shaming him. Covered in cake and lipstick, Edwin is arrested. Kristi’s mother walks away in shock—but Kristi knows she saved her from a lifetime of lies.
