Long before Betsy Ross became a national icon for making the first US flag, she was a quiet Quaker girl swept up against her will by events leading to the American Revolution.

Philadelphia, 1770. Eighteen-year-old Betsy Griscom falls in love with a man her parents can't accept-non-Quaker John Ross, whose family has strong ties to powerful colonial government offices. Despite Betsy's best intentions to stay within the safety of her Quaker world, Betsy marries John and dreams of an untroubled life with him and their future children.

Betsy's hopes are dashed when the colonies begin to openly and violently rebel against the British crown. Taught to be peace-loving and non-violent, Betsy watches helplessly as her husband becomes a militiaman and joins the resistance movement, taking them closer and closer towards chaos and revolutionary war.

When shots ring out at Lexington and Concord, Betsy realizes she can no longer be neutral. She finds herself fully entrenched in the turmoil of America's first civil war, inching closer to treason.
