As he attacks his next intended victim, Millie (Kathryn Newton) he botches the blow but the blood sacrifice means their souls are swapped.
No good will come of this.
So how about Freaky Friday but with a Jason-esque serial killer?
Blumhouse deliver this comedy body swap horror slasher well. I cackled all the way through it.
They tick all the slasher, high school and body swap boxes with a really funny script. Vaughn camps it up big style as the girl in a hulking killer's body and Kathryn Newton is quite fun as the transformed bad girl killer Millie.
Nothing here is revolutionary or unexpected they just stuck two movies in a blender but it's very good fun. 8/10 recommended.
