Grange Hill - Season 12 (1989)

It's the night of Ronnie's party, and there are unwelcome guests in the form of Trevor Cleaver and Mauler McCaul.

Chrissy is mugged on the way to school, and this prompts Miss Booth into suggesting self-defence classes. Danny starts on the swimming pool mosaic, but forgets his appointment with Mr. Tilly, about work experience.

Gonch tries to impress Mandy Freemont to get her help with the homework service - but "Les Diapositives de Bretagne" turns out not to be the musical gig he was expecting.

Mr. Bronson spoils Danny's work experience and Justine helps Tegs get his shirts clean. Trevor's got a lot of money on a horse - will "Lucky Shark" live up to the promise of his name?

Ronnie gets into Mr. Bronson's bad books when he collides with her moped. Clarke and Matthew use signalling to find the missing bike.

Trevor's out to get Vince for his failed prediction, and Mauler wants to muscle in on Gonch's Sweepstake. When Mauler and Ted chase Gonch and Ziggy through the estate, there's a tragedy in store when they discover Mr. Bronson's missing car.

Grange Hill comes to terms with Danny Kendall's death with the planting of a tree and the holding of a memorial service.

Who is hiding inside Grange Hill? Trevor has a skinful and has to be hidden away by Ziggy and Robbie. Mr Bronson, increasingly isolated and withdrawn, pulls out of the Isle of Wight trip.

Mr. Bronson changes his mind about the isle of Wight trip, Justine discovers where Tegs has been hiding, and Helen has her first day of work experience as an engineer.

Gonch sees Mandy in a new light on the Isle of Wight trip. Georgina's been getting weird notes from an admirer, and Trevor keeps losing his beer.

Trevor's drinking gets him into a dangerous situation. At the barbecue, Calley goes cold on Robbie, and Mandy discovers the original reason that Gonch asked her out.

Helen encounters Mauler at her work experience, Mr. Bronson hands in his notice and Trevor is seen going to the off-license.

Mr. Griffiths, Mauler and Ziggy make a search for the mystery intruder under the cover of darkness.

Who will be Mauler's date? Matthew and Clarke find the owner of the ferocious dog.

Mauler is out for revenge on Gonch. A reporter for the local radio station comes to school. Tegs goes back to his old house.

Plans are laid for the forthcoming Prom, and money is raised for Mr. Bronson's leaving present.

Grange Hill holds a glitzy end-of-term Prom. There's a clash of the Rambos, and a mission to get Georgina and Ziggy together.
