Westport Country Playhouse recently announced the staging of the world premiere of a new comedy, "Harbor," from Saturday, Aug. 28, to Saturday, Sept. 15, at the playhouse, 25 Powers Court.

The play, written by playwright Chad Beguelin and directed by the playhouse's artistic director Mark Lamos, opens with Ted and Kevin, a couple together for 10 years in a house in Sag Harbor, Maine. When Kevin's ne'er-do-well sister Donna, whom he hasn't seen in years, and her 15-year-old daughter arrive out of the blue, the pair's idyllic life changes and tensions quickly bubble to the surface.

The performance schedule is 8 p.m. Tuesdays; 2 and 8 p.m. Wednesdays; 8 p.m. Thursdays and Fridays; 3 and 8 p.m. Saturdays; and 3 p.m. Sundays.

"Books Worth Talking About," a pre-show discussion on prevalent themes in "Harbor," will take place Wednesday, Aug. 29, at 6:30 p.m. A Sunday Symposium with Beguelin will take place Sunday, Sept. 2, following the 3 p.m. matinee performance. In addition, the playhouse will offer an open-captioned performance on Sunday, Sept. 9, at 3 p.m., for the hearing impaired.
