Clare Bleecker (Bella Thorne) is nobody’s fool. While living in a small town and reeling from tragedy, she spends her nights assassinating people of ill repute. A sole purpose drives her vengeful mission, and Clare finds herself haunted by voices that lead her to commit these gruesome acts. Saint Clare fashions itself as a mystery thriller brimming with subtext; however, the prospects become a little top-heavy, and the film never quite lives up to its outsized expectations. Still, a commanding performance manages to hold the movie together, making it a riveting watch.

Driven by voices that lead her to kill ill-intended people, Clare attempts to live a quiet life with her grandmother in a sleepy town. Essentially friendless, she goes through life, shielding herself from the pain of her past. To the world, Clare appears shy but normal. What she hides is a vengeful killer on special orders. Be it from God or, at the very least, a higher power, she acts with righteous vengeance. When a recent kill sucks her down a rabbit hole, she finds herself tackling corruption, trafficking, and visions from the beyond.
