Confined to an asylum for the criminally insane for the past four years, Nica Pierce is wrongly convinced that she, maybe not Chucky, murdered her entire family. Nevertheless when her psychiatrist introduces a new healing"tool" to facilitate his patients' set sessions -- an all-too-familiar"Good Guy" doll using an abysmal grinning face -- a string of gruesome deaths begins to frighten the asylum, also Nica starts to wonder whether maybe she isn't crazy after all. Meanwhile, Andy Barclay, the currently nemesis from the initial three Child's Plays of Chucky, races to Nica's aid. But to rescue her he'll need to find past Tiffany, Chucky bride, that is going to do such a thing, however deadly or depraved, to help her beloved fated doll.
