Rigoberto Casteñeda offers up a belated sequel to his 2006 Mexican horror film KM 31: Kilometre 31, which I'm pretty confident you did not see. The first one dealt with a telepathic woman searching for her twin sister who had been rendered comatose in a rural auto accident involving the vengeful ghost of a dead mother. This would-be supernatural franchise is based (loosely) on the legend of La Llorona. In Spanish with English subtitles. 105 minutes R.
