A female slasher film

At Crestview High, Ms. Rachel Walden is the teacher every kid wishes they had — casual, witty, and compassionate. She runs the school paper like a surrogate big sister, and her five favorite students idolize her for treating them as equals.

But Rachel hides a darker side. By day she's the cool mentor; by night she transforms into "The Pie Killer" — dressed in a 1950s housewife's gown, blonde wig, and cracked china doll mask. This eerie alter ego is polite, precise, and merciless, punishing rule-breakers.

As her calling card, she leaves behind a perfectly baked pie in the kitchen of every child she kills — an offering as unsettling as it is domestic.

As more classmates mysteriously turn up dead, Rachel's newsroom protégés begin piecing together the truth — that their beloved teacher may also be the porcelain-faced phantom stalking the halls. When the mask slips, they must make an impossible choice: expose the only adult they trust, or risk being served the next pie.
