Ex-roadie-turned-pest-controller Tommy Saxondale is a laid-back guy, but he tends to explode with fury when he’s pushed too far. “I love my daughter. I love my Mustang. I love my girlfriend. I love the way Eno can paint a picture with music. I hate my ex-wife,” ex-roadie-turned-pest-controller Tommy Saxondale tells his irritating group therapist at his anger management class. His patience is being also sorely tried at work, what with staffing issues and protests from animal rights activists objecting to his latest assignment: a pigeon-cull at a local car pound. He solves the former problem by taking on a naive new assistant, Raymond, and the latter with his pellet gun.

Magz’s shop, Smash The System, is censored for displaying obscene material. Tommy fights for the right to uphold civil liberties, and to sell a poster of Prince Charles lighting his farts. Tommy and Raymond are called to get rid of mice in the home of celebrity motoring journalist Jerome Nelson. Tommy briefs Raymond on how not to hassle celebrities, except Tommy reckons himself and Jerome could be great mates. They bond briefly until Tommy blows his stack.

Deggsy, an old roadie mate of Tommy’s, comes to stay for a few days. While Tommy has long embraced the calm, suburban life, Deggsy still has a taste for whisky and an eye for the ladies – although these days the awkward question of the ladies’ hourly rate has to be addressed.

Tommy’s daughter Stevie pays a visit with new boyfriend Matt. Despite his anger-management classes, Tommy finds that Matt raises his volatile mood to yellow alert. At work, Tommy and Raymond head for a rough neighbourhood on a big cockroach job. There they meet a very weird, yet strangely familiar, character. And it’s Vicky’s birthday – she's '21 again'!

Tommy and Raymond attempt the humane removal of a squirrel from a woman’s loft. Tommy’s physical ineptitude on the job concerns him, so he goes to the local gym. Reluctant to start at beginner level, he twists a muscle in his neck and has to resort to amateur physiotherapy from girlfriend Magz.

Tommy’s Renault Kangoo gets clamped and, in an escalating series of events, he ends up taking on the mighty forces of corporate greed – in the form of Bernard Langley, boss of the new pest control business. Convinced he has uncovered a flea-related scam by Langley, Tommy goes for the high-profile exposure. What could be a triumph for the forces of integrity turns into what looks like Tommy picking on a fat guy.
