The shockingly brutal murder of a little girl in a church where she was just about to receive her first Communion sets a strong tone for terror in this disturbing horror film. The prime suspect in the death of Karen Spages (Brooke Shields) is her sister, Alice (Paula Sheppard), who happily tormented Karen by donning a mask and a raincoat to scare her. Comforting the grieving mother, Catherine Spages (Linda G. Miller), is her sister, Annie (Jane Lowry); local priest Father Tom (Rudolph Willrich); and Catherine's estranged husband, Dominick (Niles McMaster). Other characters include Father Tom's quirky housekeeper, Mrs. Tredoni (Mildred Clinton); a pair of detectives (Tom Signorelli, Michael Hardstark); and Catherine Spages' obese, cat-loving landlord (Alphonso De Noble). While the police investigation and all visual clues quickly point to Alice, director Alfred Sole manages to cast doubt on the killer's identity while the masked madman strikes several more times. About two-thirds of the way through the movie, Sole allows the viewer to see the killer. However, he smartly keeps his characters in the dark setting up a tense finale which culminates in yet another bloody slaying on holy ground before the lunatic is finally stopped.
