The event is taking place to mark the university centenary celebrations and comes at a perfect time for Heston (Owen Brenman) as he's bored and in a slump after his success in The Mikado.
Jack (Nicolas Woodman) isn't interested at first but becomes intrigued and agrees to get involved when he hears that Heston would be playing opposing counsel in the re-enactment. Who will come out on top?
