Simon Garden (Steve Coogan) is an "annoying" incompetent parole officer. Of his thousand clients, he could only point to three successes; George (Om Puri), Jeff, and Colin. He gets transferred to Manchester. Police Inspector Burton (Stephen Dillane) chases down juvenile car thief Kirsty and recovers drugs. She becomes Simon's case and claims the drugs were planted. He asks out police constable Emma (Lena Headey). At a strip club, he witnesses Burton selling the drugs and murdering his criminal partner. He escapes but leaves behind his wallet. Burton threatens him with a murder frame-up but later, he decides to take on the corrupt hero cop with the help of his clients, and the mysterious Victor (Omar Sharif).
Coogan is playing a well-meaning buffoon in a light caper police crime drama. He delivers some good comedy and a couple of outlandish gross-out jokes. Vomiting on the roller-coaster is hilarious. The movie could have staked out that area and made this utterly stupid. Instead, it tries to straddle both gross out stupidity and light caper comedy. It needs to pick how serious to treat the material. As it stands, it struggles to satisfy both high-minded and low-brow comedic tastes.
