Opening credits prologue: England in the 15th Century, torn and wracked by thirty years of struggle for power between the ruling House of Lancaster and the rebellious House of York.
Known as the Wars of the Roses, the bitter contest ended at last in complete victory for York.
Under the new king Edward, IV., and his brother, Duke of Gloucester, the defeated Lancastrians were ruthlessly persecuted.
This aftermath of civil war and its effect on his Lancastrian neighbors was grimly impressed on Sir Richard Shelton as he returned home from long service with the Yorkist army.
