Family Hardware tells the story of Willy, a man of a certain age, whose doctor tells him his heart is not healthy enough for sex. His younger wife Katherine, whose appetite is as voracious as ever, convinces him to let her try outside options. As they try to defuse their marital crisis with increasingly challenging alternatives, Willy relies on his lifelong friend Monica to run his family hardware business and keep him sane. When Brett, the sex maniac Monica fired, shows up as Katherine's new outsourcing alternative to celibacy, the solution becomes worse than the problem. But that is just the beginning of Willy's troubles, as Katherine takes her new-found liberties to the extreme.
