Mama Claus, Deck the Halls with Guts (2015)

On Christmas Eve four college kids head out in an RV to a ski resort. For fun, they decide to make a quick Christmas Eve pilgrimage to the site of a famous Christmas serial killing, the home of the dreaded Mama Claus (Susan Olsen)--who, unbeknownst to them, was recently paroled from the local psychiatric facility.
