Conspiracy: Regina v Luckhurst and Sawyer (1) Crown Court : Season 1 Episode 28

A radical young journalist and his student girlfriend are accused of conspiring to cause an explosion which rocked the offices of a local company. The prosecution is based on two pieces of evidence found at the couple's flat during a raid - a pair of plimsolls containing fragments of glass matching the glass at the company's offices, and letters written by the couple suggesting that the premises should be attacked.
