A young Lady Elizabeth Tudor, eager to experience life beyond the palace, and Henry, an orphan seeking to flee the brutal conditions that are his lot cross paths. The two are so close in age and looks that they could be twins. The freedom the Lady Elizabeth enjoys while assuming the role of a boy is tempered by the cruel realities of battle. For Henry, what should have been a brief respite from a life of deprivation becomes something more as he is drawn up into court intrigues that are just as vicious and unforgiving as the back alleys of London.

When she learns of this, Elizabeth, aided by Sir Thomas, race to undo a comedy of errors that threatens to turn deadly.
