Combining the warmth and charm of “On Golden Pond” with almost as many plot twists as “Deathtrap,” James Yaffe’s “Cliffhanger,” the second offering in the Deertrees Theatre Festival season will be presented on Thursday and Friday, August 18 and 19 at Harrison’s historic Deertrees Theatre.

After a long tenure as professor of philosophy at a small western college, Henry Lowenthal is looking forward to being appointed to an endowed chair so he and his wife can enjoy their golden years with honor and dignity. But their plans are given a rude jolt when his successor, a vindictive and ruthlessly ambitious young woman, informs him that she is not recommending him for the chair-an act of such calculated cruelty that the usually gentle professor seizes a bust of Socrates and strikes his tormentor a fatal blow.

“Cliffhanger” stars real-life couple and Deertrees’ favorites Terri Eoff and Jeff LaMarre – “Same Time Next Year” (2001) and “Talley’s Folly” (2004) – and also introduces Ellen Reif, Geoff Partel, and Todd Pate.

“Cliffhanger” will be presented at Deertrees Theatre on Thursday and Friday, August 18 and 19 at 8 p.m. Tickets are available at the Cool Moose in Bridgton, The Country Sleigh in Naples, Fare Share Co-Op in Norway, Books & Things in Bethel and at the theatre. For reservations and further information please call the Deertrees Box Office at 583-6747.
