Ali Reynolds is finally getting married to longtime love B. Simpson. They wanted a simple Christmas Eve wedding, but nothing is ever simple around Ali. Even as Ali's friends - Leland Brooks, Sister Anselm. and more - descend on Vegas, the bride-to-be finds herself juggling last-minute wedding plans and a mystery in the form of a stray miniature dachshund. Ali's grandson rescues the little dog when she's tossed out of a car on the Strip, but Ali's not in the market for a pet right now.
