Her decision to return it to its owner, the elegant and enigmatic Greta Hideg, portrayed by Isabelle Huppert, sparks a whirlwind friendship that fills a void in both their lives. What begins as a comforting bond between a grieving daughter and a mysterious widow soon curdles into a suffocating obsession. Directed by Neil Jordan, this psychological thriller masterfully tightens its grip as Frances discovers that Greta's loneliness masks a terrifying and possessive fixation.

With standout performances from Maika Monroe and Stephen Rea, the film crafts a chilling atmosphere of urban isolation and mounting dread, exploring the terrifying consequences of a friendship taken to its most dangerous extreme.
