It is the end of the First World War, and thirteen-year-old Meredith yearns to become a teacher. But she must leave school to help support her family, moving to the city to work as a maid in a wealthy doctor's home. As the deadly Spanish Flu sweeps across the city, members of the household fall ill one by one. With the doctor working night and day at the hospital, only Meredith and the doctor's children, Maggie and Jack, are left to care for them. Every day the newspapers’ lists of "Yesterday’s Dead” add to Meredith’s growing fears. When Jack becomes gravely ill, Meredith must stop fighting with Maggie so they can work together to save him. As Meredith wrestles with questions of duty and responsibility, she opens the door to a future that she thought had been closed forever.
