Forty Carats is a play by Jay Presson Allen. Adapted from the French original by Pierre Barillet and Jean-Pierre Gredy, the comedy revolves around a 40-year-old American divorcee who is assisted by a 22-year-old when her car breaks down during a vacation in Greece.[1][2] Their ensuing romantic interlude changes from a brief encounter to a potentially serious relationship when he turns up on her New York City doorstep to take her 17-year-old daughter on a date. Finding the attraction between them still irresistibly strong, she must overcome her resistance to a May–December romance while contending with her mother, ex-husband, and a real estate client who wants to discuss more than business.
