In 1770, the fuse of revolution is lit by a fateful command—"Fire!"—as England's peacekeeping mission ignites into the Boston Massacre. The senseless killing of civilians leads to a tumultuous trial in which lawyer John Adams must defend the very enemy who has assulted and abused the laws he holds sacred.

Yet a taut courtroom drama soon broadens into a stunning epic of war, as King George III leads a reckless and corrupt government in London toward the escalating abuse of his colonies. Outraged by the increasing loss of their liberties, and extraordinary gathering of America's most inspiring characters—Ben Franklin, Sam Adams, John Adams, George Washington, and others—confronts the British presence with the ideals that will change history.
