Investigative reporter Chris Morris puts modern Britain under the spotlight, and smacks the issues of the day till they bleed. He tackles weighty issues including animals, drugs, sex and skewered celebrities and politicians alike - and in a later episode in 2001, paedophiles.

Adapted from Blue Jam, a late night radio show, Jam consists of six shows featuring dark humour and unsettling sketches unfolding over an ambient soundtrack. From the mind of Chris Morris.
