Vanya and Sonia, two middle-aged siblings begrudgingly named after Chekhov characters, are living an uneventful life in Bucks County, Pennsylvania. The days are filled with predictable routines until their movie-star sister Masha arrives, accompanied by her charming (and incredibly attractive) young lover, Spike. Suddenly, their dull existence is turned upside down as old tensions resurface, leading to a weekend of uproarious chaos, unexpected romance, and unforgettable moments.
