Will Denton, a former Army doctor, reluctantly assumes his father’s small town medical practice in the Adirondack Mountains while his father recuperates from a stroke. Small town medicine quickly becomes more challenging than he had anticipated when local children begin dying of a horrific disease. Panic grows as the epidemic spreads. Fearing that he and others may already be infected, Dr. Denton teams up with his father’s nurse and a former Army colleague from USAMRIID, the Army’s biological warfare defense labs. Together they race to investigate the cause and attempt to control the spread before the disease causes a global crisis.
