The Cook (2008)

Over a long holiday weekend, unable to escape the confines of their sorority house, a handful of unsuspecting girls are left behind to enjoy the quiet sanctuary. The normal house staff has taken off for the weekend, leaving the girls to fend for themselves. Thankfully someone was kind enough to send them a temporary replacement chef to cook their meals. However, when the girls start disappearing one-by-one, they begin to suspect something may not be quite right.
