Be careful what you wish for. It's a Wonderful Knife's Winnie should have heeded that warning. Blending It's a Wonderful Life with Scream 2, the holiday slasher film opens on Christmas Eve in the quiet town of Angel Falls, as a masked killer goes on a bloody rampage. This psycho's tools of trade include a dagger and various festive paraphernalia. Teen Winnie witnesses the murder of her best friend, Cara, before taking down the fiend and unmasking him.
