A Chilling Family Thriller About Grief, Paranoia, and the Monsters We CreateA suspenseful and emotionally charged horror-thriller, No dejes a los niños solos (Don’t Leave the Kids Alone) follows two young brothers left alone for one night — a night that turns into a nightmare of mistrust, hallucination, and paranoia. With grief and guilt as its true villains, the film blurs the line between psychological trauma and supernatural terror, delivering a haunting reflection on childhood fears and fractured families.

The story follows Cata (Ana Serradilla), a recently widowed mother who must leave her sons home alone overnight. What begins as innocent sibling mischief devolves into paranoia as each boy starts to believe the other is plotting to kill him.
Critics at the Brooklyn Horror Film Festival and Grimmfest 2025 praised the film’s slow-burn intensity, clever cinematography, and unsettling performances by child actors Juan Pablo Velasco and Ricardo Galina. Its balance of domestic realism and supernatural suggestion has made it a standout in this year’s Latin American horror wave, earning early festival buzz and international distribution.
