Kurt, Brian, Penny, Matt and Lindsay are the teachers no parent would want teaching their kids. And they're back for the 3rd series that sees them making friends, falling out, trying to figure out the opposite sex, smoking in the playground... and dealing with lippy pupils. It's business as usual for the young teachers specialising in immaturity rather than the traditional subjects. Brian and Kurt are still dreaming of getting laid, and they've met their match with new biology teacher Lindsay - she can drink a pint in 1.3 seconds, she likes curry and she can out-blunt any of the boys! Back in the photocopier room, Matt (married with kids) and Penny have managed to find the perfect work/play balance and are enjoying some extra curricular activity of their own. And what of everyone's favourite teacher who quit teaching to go travelling in the last series? Andrew Lincoln returns as Simon, and he doesn't receive the welcome he had hoped for when he surprises his old mates.
