Saint Maud is a 2019 British psychological horror film written and directed by Rose Glass in her feature directorial debut.

The film stars Morfydd Clark as a religious private carer who becomes dangerously fixated with saving the soul of her patient.

Saint Maud premiered at the Toronto International Film Festival on 8 September 2019, and was released theatrically in the United Kingdom on 9 October 2020 by StudioCanal.

It received critical acclaim, with particular praise for Glass' direction and screenplay, the performances of Clark and Ehle, and Fordesman's cinematography.

Some time later, Katie, now referring to herself as Maud, has become a devout Roman Catholic and is working as a private palliative care nurse in an English seaside town.

She is assigned to care for Amanda, a hedonistic former dancer and choreographer from the United States who is terminally ill with stage four lymphoma.

That night, Maud, dressed in a makeshift robe and wearing rosary beads, enters Amanda's house after the care nurse leaves.

In her last moments, angel wings appear upon her and the onlookers kneel in awe as Maud looks up to the sky glowing with grace.

The website's consensus reads: "A brilliantly unsettling blend of body horror and psychological thriller, Saint Maud marks an impressive debut for writer-director Rose Glass.

Striking, affecting and mordantly funny at times, its confidence evokes the ecstasy of films like Carrie, The Exorcist, and Jonathan Glazer's Under the Skin.

[26] In a review for Common Sense Media, Danny Brogan wrote, "A deeply unsettling, yet superb first feature film from director and writer Rose Glass, this psychological horror is far more than just jump-scares – though there are plenty of those too.

Maud is a deeply lonely character, whose need for redemption and a desire to belong, all contribute to form a dangerous cocktail with devastating consequences.
