Maria Mileaf (Going to St. Ives) stages the New York premiere of the work that officially opens Oct. 14 and continues through Nov. 16.

Michael Cristofer and Laura Odeh join Lahti onstage in the three-character piece. (Lahti and Cristofer replaced originally announced performers Margaret Colin and David Rasche).

"Who are we without our memories?," poses A Body of Water show notes. The drama begins as "Avis and Moss awake one morning in a house set in the forested hills above a picturesque body of water. The weather's great, the view's magnificent. However, neither of them seems to know whose house this is or who they are. Will the stranger at their doorstep be able to help?"

An Emmy and Golden Globe Award winner for her turn on television's "Chicago Hope," Lahti last appeared on the New York stage in 1990's Broadway run of The Heidi Chronicles. She appeared recently in another Wendy Wasserstein work, Third, at Los Angeles' Geffen Playhouse.
