Middle-aged Vanya and his adopted sister Sonia live a quiet life in the Bucks County, Pennsylvania farmhouse where they grew up.  Their peace is disturbed when their movie star sister Masha returns unannounced with her much younger boy toy, Spike.  Old resentments flare up, eventually leading to threats to sell the house.  Three siblings.  One hot mess.  Also on the scene are the sassy maid Cassandra, who can predict the future, and a lovely young aspiring actress named Nina from next door.  A weekend of rivalry, regret, and raucousness begins!
