Known for its luxurious accommodations and bespoke service, the Hotel Louis XVI has been the most lauded boutique hotel in all of Paris for decades, attracting an international clientele of the rich and famous. Now, after four years of renovations and the death of its legendary and beloved manager, it is set to reopen its doors at last. An esteemed group of loyal returning guests is set to descend upon the hotel, joined by a number of new faces who have managed to secure coveted bookings in the wake of last-minute cancellations. Awaiting them all is the Louis XVI's new manager, Olivier Bateau, an anxious man whose lack of experience leaves him unprepared. He and his level-headed assistant manager, Yvonne Philippe, both strive to continue the hotel's tradition of excellence. But they quickly realize that anything can happen at any moment, and on one cool September evening, everything does. A successful art consultant arrives at the hotel for the first time since her brutal divorce, and is surprised to find new love--if she is willing to risk her heart again. A new guest contemplates ending his life, and saves a life instead. A couple finds their once-in-a-lifetime trip interrupted by a tragic medical emergency, leaving the idyllic future they've long waited for hanging in the balance. And one of the hotel's most high-profile guests, a French politician and assumed presidential candidate, holds a mysterious meeting in his suite that will threaten his life and legacy. Rocked by the events of this one fateful night, guests and staff alike brace themselves for the aftershock, as it quickly becomes apparent that more dramas and misfortunes are still in store.
