The official website for Final Remains (Mortuary) is online

"Final Remains" is the new title of the movie in question; "Mortuary" was its original title.

The screenplay was written by Hazelaar (a.k.a. Shawn Hazeleur), and tells the story of Deerhaven, a city that has been burdened by disappearances for more than two decades and local officials have come up empty as no trace of the missing have ever been found.

An eccentric psychiatrist with questionable credentials comes to town implicating the local mortician, Henry Parks. Claiming to be Henry's former doctor from a facility where Henry had been institutionalized, Dr. Gronig suggests that the mortician may not have been suitable for release and may be using his father's parlor as a cover for deeper, darker things.
