Colleen Foy carries the film as Sarah, the midwife. Her arc isn’t about screaming or panic, it’s about watching professional certainty dissolve in real time. She arrives skeptical, grounded, rational. She leaves as something else. What makes this work is that Foy never telegraphs the shift. It’s subtle. It’s the way her composure fractures incrementally. By the end, you’re watching someone who has been touched by something that shouldn’t exist, and her face tells you she knows it.

Colleen Foy came out of nowhere for me with a rather heartfelt performance. Really hoping to see her in more things! I think they work brilliantly off each other in the complications of this pregnancy in the woods.

TV veteran Foy is particularly good in what appears to be her most substantial feature film role to date. Foy really sells the mixture of compassion and frustration that Sarah feels towards Goody, who put herself in this situation by ignoring the midwife's learned advice.

Foy’s Sarah convincingly channels the mounting dread of a well-meaning caregiver caught between her patient’s demands and her own better judgment.
