A hard-hitting play about the collapse of idealism in contemporary politics. The founder members of a radical think-tank meet to toast their success – fifteen years of second-guessing the next big idea; fifteen years of shaping politics on the left; fifteen years of thinking the unthinkable. But there's a spectre at the feast, and a scandal is about to break that will ruin more than just the party. Steve Waters' play The Unthinkable was first staged at the Crucible Studio, Sheffield, in 2004.
