Yiya2025

Horror Vault's take

Based on one of Argentina's most notorious real-life criminal cases, Yiya pulls viewers into a chilling reconstruction of how an ordinary woman allegedly became a calculating killer. A determined journalist digs through decades-old secrets, piecing together the events surrounding a series of poisonings that stunned 1970s Buenos Aires. The series lingers on the disturbing gap between domestic normalcy and cold-blooded intent, asking what — and who — we truly know. Equal parts crime procedural and psychological portrait, it's a slow-burn descent into one woman's dark psychology.
