 Mandy Freemont is the keystone in Gonch & Ziggy s computerized homework service, so Gonch is out to impress her - surely the huge volume of Les Miserables on his desk will help? Helen pursues her interest in engineering, with some work experience in the offing. Miss Booth s self-defence class hits a snag with union rules about overtime. Still finding their day-to-day activities, dogged (so to speak) by the ferocious Alsation, Clarke and Matthew use the tower block to survey the area using binoculars. They spot Clarke s lost bike - and dash off in pursuit down the stairs. When they get to the spot, the bike is no longer there - and Matthew realizes he left the binoculars at the top... Ziggy and Robbie find Mandy outside the community hall, where they find what appears to be a pop group called Les Diapositives on in the evening, as part of the French Club - they tell her that Gonch is interested. Mrs. McClusky and Danny come to a new working agreement - including Danny s extra requirement "Keep Bronson Off My Back" in big bold letters! The sport of Street Hockey (hockey on roller-skates) becomes very popular, and a boys versus girls match is held. Trevor uses it as way of getting back at Ziggy, who s become his rival for Georgina (except she continues to have absolutely no interest in Trevor), but after tripping Ziggy up, Mr. Robson kicks him out. Gonch attends the community centre to see the band "Les Diapositives de Bretagne", to further his aim of bringing brain-box Mandy on board for the homework scheme. He takes a seat next to Mandy, and Ziggy and Robbie creep into the back of the hall. To their surprise, what follows turns out to be a presentation of slides by Mr. Bronson - his holiday in Bretagne - given in French!
