While still grieving over the murder of her son, Joanna Portman (Kim Hunter) is visited by a young girl (Gretchen Corbett) claiming to her daughter Gail--who for several years has been presumed dead. Though Joanna is delighted by the girl's arrival, Ironside suspects that Gail's sudden reappearance is too good to be true. Sure enough, it turns out that there are sinister forces who are trying to kill off Joanna's entire family...and that the girl calling herself Gail may be at the center of the carnage! ~ Hal Erickson, Rovi
