Chiropractor and single father Alan Harper lives in a beachfront house with divorced Internet billionaire Walden Schmidt, who bought the house following the untimely death of Alan's brother, Charlie. As they acclimate to their living arrangement, the tightly wound Alan finds himself taking on a mentor role with Walden, whose lifelong dependence on being taken care of has left him a bit naive. Despite his unsuccessful romantic history, Alan also tries to help Walden overcome his limited experiences with dating. Berta, a sharp-tongued, unapologetic housekeeper, is also featured in the series.

In an attempt to prove that he is a family man, Charlie invites Lisa (Denise Richards) over for Thanksgiving dinner.

Alan seeks revenge when he discovers that Charlie stole his high-school girlfriend.

Judith is pregnant with a baby girl, and Alan is convinced he is the father; Jake is in a contentious mood, and Charlie thinks he knows why.
