Doug Heffernan puts in a long day's work delivering parcels and comes home each night to his loving wife, Carrie; unfortunately, he also comes home to his wacko father-in-law, Arthur.

Doug and Carrie's friendship with Deacon and Kelly is tested after Doug is distracted and backs into their car.

Arthur is left to fend for himself when Doug and Carrie go on her company retreat with a group of boring lawyers.

Doug's Halloween decorations put Arthur in the hospital; Deacon doesn't like Kirby's choice of a Halloween costume.

After Carrie tells Doug that it's okay for him to find other women attractive, he asks her to tell him which men she finds attractive. Unsurprisingly, this doesn't end well.
