It does have a ring of that story in it. It also reminds me of Bring Me Back Her Bones (I think - could be mixing it up with another show), where a couple are in Haiti, and the man tries to "send" his wife's body or spirit to some unknown time so that she'd no longer exist now. He just had to keep her bones. Of course, it's all a sham set up by his wife because she knew he was trying to kill her. Something happens to him where he's basically catatonic but aware, and she says that she'll stay with him.....forever, just to make sure he's taken care of.....YIKES!
Of course, I may be mixing 2 plot lines here, I can't remember. But a good revenge story nonetheless.
