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.

Judith leaves Jake with Alan and Charlie while she spends a week in Hawaii, and the guys find that caring for Jake on a daily basis is much different from weekend visits.

Alan plans Evelyn's wedding; Charlie pursues his future stepsister.

Charlie plans a romantic date with Mia in hopes of consummating their relationship; Alan starts dating Charlie's most recent ex-girlfriend.

When Charlie finds he can no longer handle the healthy lifestyle that Mia has imposed on him, he sneaks cigars, beer and burgers into the garage.
