Trampa mortal

This is a pretty typical low budget horror movie for the early 70s with twists and turns leading up to a surprise ending. You'll see alot of that. If it's not Terror at the Red Wolf Inn with cannibals or Legacy of Blood with deaths following the reading of a Will, it's mysterious invitations to a cult meeting years after a tragic event occurred regarding one of their members? Were they summoned by one of the members? A relative of the slain? Both? Neither? They almost all have a twist ending. One of the few that didn't was Invasion of the Bee Girls now that I think about it...

This has a really small budget but that works to the advantage of these types of movies. It gives them a grainy unnerving feel with every ugly frame.

It's pretty well acted and moves along at a good pace despite the fact that these sorts of stories do tend to drag.

Not half bad for the genre. Not sure why they only have the one title listed for it. I know it as Sisters of Death.
