Mission: Impossible - Christmas Undercover, Elena Petrea Kyrintzis Ava never wanted to be the center of attention. And even less would she have wanted to spend the weekend before Christmas in Las Vegas, at her sister's bachelorette party. But under pressure from her family and with the thought of not spoiling the joy of the event, she embarks on a trip that she believes will be short and, she hopes, as tumultuous as possible. The surprise arrives at the airport, where she meets a long-lost figure - Grandma Eleanor, who is far from being an ordinary grandmother, but rather a queen of fun, Eleanor attracts glances and causes murmurs everywhere she goes, and Ava feels that this weekend will be crazier than she could have ever imagined. Arriving in Vegas, Ava tries to stay away from her grandmother's endless adventures, but things quickly get out of hand when she meets Enrique Navarro. Charismatic, mysterious, and with a smile that promises danger and fun in equal measure, Enrique has a hidden agenda – he’s in Vegas on a secret mission, tracking down a dangerous ring. Ava finds herself drawn into his plans sooner than she thought, and their bond grows stronger. As Ava and Enrique navigate the city’s lights and the dangers of his mission, a series of crazy events test their courage and the attraction they feel for each other.
