The Spanish-language psychological horror film Crazy Old Lady is now streaming on Shudder as of February 27.

Directed by Martín Mauregui in his feature debut and produced by J.A. Bayona (The Orphanage), the film follows a man who agrees to temporarily care for his ex-girlfriend’s senile mother. What begins as a small favor quickly spirals into something far more disturbing, as he’s forced to play along with her increasingly sadistic games.

Carmen Maura stars alongside Daniel Hendler and Agustina Liendo.

The Spanish-Argentine co-production premiered at Fantastic Fest, where Mauregui won Best Director in the Horror Competition, and later screened at Sitges.

Crazy Old Lady is available now on Shudder and AMC+.
