What Happens at Night is a haunting horror-mystery that masterfully blends psychological tension with atmospheric dread. The film follows an American couple who journey to a remote, snowbound European town with hopes of adopting a child. Their destination—a grand yet decaying hotel—becomes a character in itself, its labyrinthine halls and eerie silence amplifying their growing unease.

Director Peter Brunner crafts a meticulously unsettling atmosphere where reality becomes increasingly fluid. The couple's encounters with the hotel's bizarre residents—a melancholic chanteuse, an enigmatic businessman, and a mysterious faith healer—serve as disturbing mirrors to their own fractured relationship and unspoken regrets. As they pursue the elusive adoption, their grip on sanity and purpose begins to unravel, leading to chilling revelations about themselves and the shadowy forces at play.

The performances are deeply compelling, with the leads portraying a marriage strained by quiet desperation and unspoken grief. Brunner's direction is patient and immersive, using long takes and stark cinematography to build a sense of profound isolation and creeping horror. The film is less about jump scares and more about the psychological erosion of its protagonists, making it a thought-provoking entry in the arthouse horror genre.

Viewers should watch What Happens at Night for its unique, slow-burn approach to terror. It's a film that lingers, posing unsettling questions about parenthood, identity, and the ghosts we carry. Perfect for fans of atmospheric, character-driven horror like The Witch or The Lighthouse, this is a cinematic experience that challenges and chills in equal measure.
