Shakespeare & Company presents “A Body of Water” by Lee Blessing

Moss and Avis, a sophisticated and successful couple, wake up one morning in an isolated summer house high above a picturesque body of water. The weather’s fine; the view’s magnificent. There’s only one problem — neither of them can remember who they are. When a young woman named Wren arrives, information starts to flood in. But will it help? Her explanations seem only to make Moss and Avis’ world — as well as ours — more terrifying.
