Alf King and The Gang are horrified when they are called for Jury Service seeing it as a Plot to ruin their (Criminal) reputations. Eleanor comes up with a cunning plan to hide this - which necessitates two cover-plans. One for the Regulars - and police informers, the other for Martha and Myrtle. She arranges for The Gang to be Security Guards supporting her in 'house-sitting' Mr.Carmichael's mansion while her Boss is away on holiday. On almost their last day they are on the Jury for the trial of the Hon. Michael Seafrood - with whom Alf had had dealings in the past. The mansion is raided by a bunch of Protesting Students, then by a Mob of Masked Raiders. The Students, now defending the mansion, capture all the Masked Raiders but police, including DS Cuthbertson and DC Wilde suddenly arrive on the scene, arrest everyone including the Students, Alf and Eleanor. Mr. Carmichael arrives home early but it still takes all Alf's ingenuity to get all the 'Deserving' let off.
