The makers of this decent horror drama do get high marks for good intentions here. Their film does score to a degree by focusing on the human element, as the devastating effects of tragedy hit a young country dwelling couple. This couple, Alan (Malcolm Stoddard), and Kate (beautiful Cyd Hayman), already have four children of their own. They meet a mysterious, pregnant stranger (played by Angela Pleasence, the daughter of Donald P.) who gives birth in their home and promptly disappears. They keep her baby as one of their own, but their own children start dying under mysterious circumstances, starting with their infant. Alan comes to believe that the new kid, Bonnie (played at different ages by Wilhelmina Green and Joanne Boorman), is responsible, but Kate just can't accept that this adorable moppet could possibly be a danger.
This may be too slow and quiet to suit some horror fans expecting something more along the lines of "The Omen". It really does stress its dramatic elements more than anything, shying away from anything such as graphic violence. It does have a suitably eerie mood, beginning with the effectively enigmatic performance by Ms. Pleasence. The rest of the cast, including Patrick Barr as the sympathetic Dr. Collins, does fine work. Location shooting is good and atmosphere is strong but the music by Roger Webb is a little overbearing. The script is by Olaf Pooley, based on a novel by Bernard Taylor, and the film is dialogue heavy, with producer / director Gabrielle Beaumont (making her feature debut here) never rushing through the story. The ending fails to be completely satisfactory; in fact, it's kind of abrupt, but overall those genre fans who prefer subtlety may find it to their liking.
Six out of 10.
