Disappeared (Acting Edition)

This mysterious, starkly modern award winning play concerns Sarah Casey, a 25-year-old travel agent who has never been outside New York City. She goes missing after leaving a seedy bar in Hell's Kitchen , where the last person to see her was Elston Rupp, a man who works in a thrift shop and dresses in his clients' clothes to assume different identities. Was Sarah killed, or did she merely "disappear" to escape her anonymous existence in a big lonely city?
