A woman is found dead in her house at eleven o'clock this morning and there doesn't seem to be any apparent reason for her death. The coroner, Ken Griswald said that there is always a cause of death and takes on the case. However, the corpse is that of his wife Helen, and though he can find no cause he is determined to discover what has happened to her. It seems to him that it is as though she were not dead and more so when she comes back to haunt him after her burial.
