On Golden Pond

Norman and Ethel Thayer are looking forward to another tranquil summer spent on the lake, but their adult daughter Chelsea has other ideas. She plans to bring her new boyfriend Bill along to celebrate her dad's birthday, but what she doesn't announce is that Bill's teenage son Billy Ray will be tagging along. Norman and Chelsea have had a rocky relationship over the years, but the visit is mostly pain-free — at least until Chelsea asks if Norma and Ethel can take care of Billy Ray for the rest of the summer while she and Bill head to Europe. Ernest Thompson's On Golden Pond captures a family in transition: Ethel and Norman are approaching the end of their lives, while Chelsea is simultaneously stuck in her unhappy past and eager to face the future. Insight Theatre Company presents On Golden Pond at 8 p.m. Thursday through Saturday and at 2 p.m. Sunday (July 6 to 23) at .Zack (3224 Locust Street; www.insighttheatrecompany.com). Tickets are $20 to $35.
