Given that heroine Heather Locklear is rich, neurotic and semi unhappily married to a much poorer man (Robert Carradine), it's not hard to work out when strange figures start menacing her in an isolated location that this is going to be one of those it's-all-a-plot plots.
And given that the supporting cast includes Ned Beatty as a jovially drunken handyman and Emma Samms as Carradine's suspiciously svelte sister, it's also not too hard to work out who exactly is in on the vile scheme. What is hard to figure is why Susannah York would accept a one-scene cameo in such a deeply forgettable and tedious thriller and why the screenwriter thought anyone would be fooled.
