It revolves around a businessman anti-hero, John Weak (Alexander Armstrong), whose main attributes are summed up in the words "randy, sexist, and drunk".
Weak is the Marketing Director of Smokehouse plc, a global corporation which turns "food you wouldn't give to your dog" into snacks and other packaged and processed items.
Smokehouse's actual products are irrelevant to John Weak, whose objects in life are to have the best car, bed the hottest women, and be top dog.
Thick-skinned personal assistant Hayley (Clare Perkins) fences with her boss John constantly.
When the squeeze is really on, John turns to his "Director of Long Lunches and Work Avoidance", Bill Peters (Ron Cook), who can be counted on to rescue the situation with a brilliant scheme, usually after he is well into the second bottle of claret.
