During a sorority initiation, one of the pledges is shot in the head and killed. Years later, the other sorority sisters receive mysterious invitations to an isolated house. As it turns out, the house is owned by the father (verteran actor Arthur Franz) of the girl who was killed . . . and he wants revenge.
This movie is pretty dull (it's rated PG and other than a few minor scenes it could have been a TV movie of the week back in the 1970s). But it does feature the late Claudia Jennings as one of the sorority girls.
The version I have is in Mill Creek's CHILLING CLASSICS 50 MOVIE PACK. The color is somewhat washed out, but it's still very watchable (that is, if you MUST watch it).
