Power commands. Love defies. History judges.

'A vain and indecent woman,' they said.

England, 1341: When the young Joan of Kent is married at Westminster Abbey, the ceremony binds her not just to a husband, but to a royal lie. By order of her uncle, King Edward III, Joan becomes the first - and only - English princess to knowingly commit bigamy.

The marriage is meant to end a dangerous dispute and secure the Crown’s authority. Instead, it ignites a decade-long struggle that pits one woman against her family, her king and the laws of England itself.

Joan is no ornament of the court. Intelligent, resolute, and fiercely independent, she refuses to surrender her claim to the man she believes is her true husband - even as pressure mounts and punishment looms. Everyone expects her to yield. She does not.

Told through the watchful eyes of her long-dead father - a knight bound to honour, duty, and silence - this is a powerful true story of loyalty and defiance in an age when love could be treason and obedience a matter of survival.
