I’ve been struggling with this one for years. I was probably around 5 when I seen this movie on TV so that would put the year around 1995. I can’t remember much of it. But what I do remember is a man killed his wife and buried her in the backyard, I remember a dog digging up her hand and bringing it to him (I think), and I remember her zombie self stalking him around the house. She may have had a blueish face from being dead.
Hope you can help!
