A comedy about the members of the local amateur dramatic society, the Off-the-Wall Theatre Company (none of whom bears any resemblance to anyone you might have met). The ‘Big Idea’ in question is a new television series, where a lucky person gets the chance to fulfil a great ambition. In this case, the Off-the-Wall company’s director, the egotistical Jonathan, has harboured a dream of writing a masterpiece for the stage. The TV series gives him the chance to have his play broadcast on national television – with the help of the other members of the Off-the-Wall Theatre Company, who do not necessarily share Jonathan’s view of his abilities.
