Three sisters, Agatha, Tabitha and Samantha, have shared a dark secret from their childhood. Ten years ago, their six year old stepsister Tammy drowned in the bath tub from a prank gone horribly wrong. Though it was ruled an accident, the three girls, now grown women, know it was much more than that. They should have confessed, but they vowed with each other never to tell a living soul what really happened that fateful night. Now, the lovely doll that Tammy once cherished has mysteriously appeared in each of their homes. And a nightmare of unspeakable revenge will soon befall them one by one. Has Tammy's spirit returned to exact vengeance?
