Bloody Birthday 1981

On 09 June 1970, three babies are born on a day of eclipse of the sun. Ten years later, Debbie Brody, Curtis Taylor and Steven Seton are always together and form an evil gang. Out of the blue, they start a crime spree killing initially two sweethearts in the cemetery. Then they kill Debbie's father Sherriff James Brody; their school teacher Miss Viola Davis; a couple in a van; and Debbie's sister Beverly Brody. They try to kill the boy Timmy Russel (K.C. Martel) and his teenage sister Joyce Russel in a junkyard, but they fail in their attempt. Now they are hunting down the siblings.
