Channel 4's most successful ever drama series returns to DVD for an unprecedented fourth series. Following the lives, loves and timetables of a group of hapless teachers that no sane parent would want teaching their children, this irreverent comedy drama continues to steer clear of anything remotely educational or politically correct!

Starring Tamzin Malleson as the manipulative sex kitten Penny; Vicky Hall as lardy Lindsay, the biology teacher with a healthy disregard for her pupils; Lloyd McGuire as "new" Bob, having reinvented himself on the cusp of a mid-life crisis; Ursula Holden Gill as squiffy-eyed Carol; Ellen Thomas as scary Liz; and Gillian Bevan as the head teacher Clare.

This release contains episodes 1-9 of Series Four.
