Paper Dolls (1968)

One of Craig Miller's pupils has three identical brothers who can communicate telepathically despite living hundreds of miles apart and who are capable of controlling people's minds, often with fatal results. Craig and fellow teacher Jill find the brothers have gathered at a small isolated village, home to the dominant sibling, a deranged and unbalanced boy who was abandoned at birth but has survived by scavenging in the village. The villagers are intent on killing him as he has caused havoc and destruction to their lives and property. But will their thirst for blood lead to a massacre of all four children?
