A young man, in love with a woman who can never be his, discovers a way to fulfil his dreams. In their childhood the three were the best of friends, the perfect triangle. But years later when Lena returns to her sleepy home the tone of the relationship changes and it is Robin she loves. Bill has discovered a method of duplication and decides to make an exact replica of the woman he cannot have... .with disastrous consequences for them all.
For a while, this first Hammer sci-fi offering is actually quite interesting: two childhood friends develop a machine that can replicate anything - animal, vegetable, mineral - you name it. When "Robin" (John van Eyssen) marries their childhood friend "Lena" (Barbara Peyton) his co-developer, "Bill" (Stephen Murray) contrives to makes an identical version of his own whom he calls "Helen". Now the fly in his ointment is that "Helen" is too good a duplicate - unfortunately she loves his mate too - and so poor old "Bill" is faced with a real dilemma. The story is quite fun, but the acting is pretty mediocre and the dialogue a bit too staccato to keep the story flowing. The effects, such as they are, are a bit on the basic side too with sets that wobble and glow like an old edition of "Dr. Who". It's not terrible, and as a first effort in his genre from a studio far better versed in horror genres, is an ok watch from writer/director Terence Fisher.
