Morfydd Clark plays a newly devout hospice nurse who becomes obsessed with saving her dying patient's soul.
Get ready, because the horror film of the year has arrived.
Saint Maud follows Maud (Morfydd Clark), a private nurse who moves into former dancer Amanda (Jennifer Ehle)'s house to provide hospice care as she battles cancer.
Maud is quiet, reserved, a little strange and is harbouring a secret about her past that made her recently turn to religion.
The newly devout nurse is convinced she can feel and hear God and becomes dangerously obsessed with saving her dying patient's soul.
Rose Glass' assured directorial debut is an intriguing blend of unsettling psychological thriller and genuinely horrifying body horror that is most definitely not for the squeamish.
Saint Maud stands out from the crowd because it's not a cheap horror that is solely designed to dole out shallow scares - Glass focuses more on developing the story, who Maud is, and her relationship with Amanda before pulling the rug out from under us.
This means that when the scares do come in - particularly in the last 30 minutes - they are all the more terrifying, shocking and effective because they are well earned and we care about the people involved.
Glass creates an intense, creepy atmosphere to accompany her story by employing a clever sound design and a thumping soundtrack to really help build the tension, sense of foreboding, and give audiences an eerie, unsettled feeling, with us wondering where the story is going to go or what Maud is going to do next.
Glass loses her grip on her audience briefly around the hour mark but she brings it back in no time before driving it all home in a sensational and terrifying finale that will stay with you for hours after you've left the cinema.
Clark cannot be praised enough for this role, which required serious emotional and physical work.
Maud begins as this restrained enigma and while we’re never given her entire back story, we have enough to work with.
Clark gives Maud humanity even when she truly loses the plot and becomes a danger to herself and others.
If you're a fan of horror, Saint Maud is definitely worth checking out. It'll make you wince, jump and get your heart pounding like crazy.
Certain imagery will be firmly lodged in your brain a long time after a watch.
