The play consists of four parts, with a monologue making up each part. The monologues are given, in order, by the faith healer, Francis (Frank) Hardy himself; his wife, Grace; his cockney manager, Teddy, and finally Hardy again.
The monologues tell the story of the faith healer himself, including an incident in a Welsh village in which he cures ten people. Teddy's monologue reveals that Grace Hardy commits suicide, while Frank ponders whether his gift is for real or not.
It was again revived in 1994 at the Long Wharf Theatre under the direction of Joe Dowling and starring Donal McCann, Judy Geeson and Ron Cook. The New York Times called the production "incandescent" and recommended it to "any connoisseur of theater".
The most recent revival was at the Booth Theatre on May 4, 2006. The cast consisted of Ralph Fiennes, Cherry Jones and Ian McDiarmid in a production from the Gate Theatre in Dublin, directed by Jonathan Kent. The Broadway revival received four Tony Award nominations and won one: Best Featured Actor in a Play, Ian McDiarmid.
