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. Widowed mom Cate (Katey Sagal), now finds herself in the precarious position of raising three teenagers on her own. She does get a little relief from her father, Jim (James Garner), who's been staying at the house since Paul's death. 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.
