From the start you know this is going to stink when the lead asks her husband of many years "Your father doesn't know you're a diabetic, does he?", when they are IN HIS HOUSE having dinner! Presumably this didn't seem important enough to talk about before!
A nosy American doctor shows up at a remote Scottish island and without delay starts her own full scale murder investigation after she dug up a hole in her garden that uncovers a body! She immediately gets a job at the hospital, too. She must be a helluva doctor!
The bloody awful music tries to give an atmosphere of suspense for the entire 90 minutes... even when there's NOTHING HAPPENING!
The cult elements are never really explored, apart from a few daubings on walls and bodies... which the cops don't seem to think really matter.
Anyone who gets in the way is bumped off and for the cops it's just another day in the office. Happens all the time on these remote islands.
Somehow the house on the top of a mountain seems to have been FLOODED! How the bloody hell did that happen?
The final 20 minutes play out like the worst episode of a 1990's Ruth Rendell crap-fest.
Overall it's just very silly. It is Lifetime TV for people who think that Lifetime TV needs more murders!
