Two English fisherman take their boat through the fog to a lighthouse on a secluded island. They find the slain bodies of a man and a woman within-and one of them is killed by a crazed young woman wielding a gold weapon.There's an investigation by the authorities and there's no explaination of what happened. The young woman, the only survivor, is only able to recall events through a special form of hypnosis-and the viewer is shown, via flashbacks, what really happened. Did she kill her companions or is there someTHING living on the island.The surviving fisherman has all the answers but doesn't divulge any of the information until the end, but by then many people are killed.It turns out that the lighthouse was built atop an ancient burial site of the ancient Phoenicians, who worshipped a fertility god named Baal. And perhaps the power of this god has influenced whatever it is that lives on the island.TOWER OF EVIL is a really good movie. It can best be described as an 80's slasher flick as if done by Hammer Studios. Also known as HORROR OF SNAPE ISLAND and BEYOND THE FOG.
