The Marsh theater sums up the latest solo play from Brian Copeland as "a tale of privilege, murder, and sausage." It's a pretty apt description, since Copeland injects his signature brand of humor into the rather heavy subject material of The Scion whenever possible. The show is based on a real-life triple murder at a sausage factory in 2000. Stuart Alexander, who was born into a wealthy East Bay family and often referred to himself as the "sausage king," murdered three meat inspectors who were attempting to enter the Santos Linguisa Factory. Alexander later claimed that he was "provoked" by the inspectors, and often gave the impression that he believed he was above the law. Copeland takes these events and uses them as a case study to explore the roles of class, privilege, and government regulation in modern society. Keeping this funny could be a tall order, but Copeland has a knack for making the serious entertaining. One of his previous plays, Not a Genuine Black Man, was the longest running solo show in San Francisco.
