When a middle-aged divorcee returns to fulfill the dream of a college education she left behind years earlier, she finds that being the oldest student in the room may mean that she has as much to teach those around her as she has to learn from them. Four-time Emmy® nominee and three-time Golden Globe winner Cybill Shepherd (“Cybill,” “The L Word”) and “24” season seven star Jeffrey Nordling star in “Mrs. Washington Goes to Smith,” a Hallmark Channel Original Movie premiering Saturday, August 1 (9/8c).
