Clancey McCauley stars as twins, one of whom plans the murder of the other. While the Valley Strangler terrorizes the local town, the bad twin plans to make it look like her sister’s murder is at the hands of this serial killer. "Sisters" was filmed mostly in 1987 and was the very first feature from W.A.V.E. Productions. It was first sold through mail order only under the title Stalked in 1988. New footage was later added and it was reissued again as "The Valley Strangler."
