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's only refuges are the little time he spends alone with Carrie and the company of his buddy Spence, co-worker Deacon and cousin Danny, whom he turns to for advice that just might make his life better, if he only bothered to follow it.
