A gang of four criminals have raided a warehouse and a night-watchman has been shot and seriously wounded. Two of the gang have been acquitted of attempted murder at an earlier trial. The third member of the gang is now on trial after finally being apprehended in Essex. The fourth gang member, the getaway driver, has turned Queens evidence in return for police protection and is now being used as a prosecution witness. Is his evidence reliable enough?

Barrister Helen Tate attempts cast doubt on evidence given by nightwatchman Joseph Pearson. She maintains his evidence may be tainted due to injuries inflicted during the robbery. Albert Duffy begins to give evidence in his defence.

Albert Duffy claims he is a changed man since his first child was born while he was in jail. Although he doesn't deny he took part in the robbery he claims he was coerced by Terrence Manning. He now faces cross examination by Barry Deeley.
