In this Light is an adaptation of An Enemy of the People by Henrik Ibsen. Dr. Thomasina Burke is a well-respected medical doctor in a rural village in the Annapolis Valley in 1931. Just as her hometown is poised to reap the benefits of an important new business--a health spa that will bring people from far and wide--Dr. Burke makes a discovery that will challenge her whole community to choose sides in a battle over the very nature of truth, and the power of one person to be heard.
