Portland Playhouse offers Sharr White’s riveting psychological drama that Backstage described as a “taut, incisive puzzle play.” Powerhouse biophysicist, wife, and mother Juliana Smithton is accustomed to being the smartest person in the room—and to getting her way. Smithton has achieved great success as a pitchwoman for pharmaceutical companies, specializing in drugs that combat dementia. But after an episode of minor confusion, Juliana discovers that she might be suffering from medical troubles that painfully resemble the focus of her own research. If her own mind is playing tricks on her, who can be trusted? Performances from November 13 through December 8. Check showtimes and reserve tickets through the PP website.
