It's a time for healing and learning to deal with life without family patriarch Paul (the late John Ritter), as the Hennessys discover the frailties of life and the strength of the family unit, on 8 Simple Rules. Cate (Katey Sagal) now finds herself in the precarious position of raising three teenagers on her own while holding down a full time job as a hospital nurse near their Detroit-area home. She does, however, get a little relief, thanks to her father, Jim (James Garner), who's been staying at the house since Paul's death. Retired and separated from his wife, Jim mostly spends his days making home improvements to the house - with arguably mixed results - and, in his own inimitable way, gives comfort and guidance to his daughter and grandchildren during their time of need. But the family is thrown for a loop when Cate's wayward nephew, C.J. (David Spade), moves in and finds it hard to resist getting himself into trouble or offering questionable advice to the kids.
