A long hot summer, thirty years into the reign of King Henry VIII, and well into middle age, Henry takes his fifth wife, Katherine Howard. The Queen's "low background" combined with her youth and beauty, arouses a lusty familiarity in certain members of King Henry's court most notably his handsome young servant Thomas Culpepper.

Rejuvenated by his tour of the north of England, Henry feels a new man and longs after his new Queen; unaware that her affections are diverted elsewhere. Katherine’s past begins to catch up as an old liaison comes looking for a job threatening to reveal all about their sexual history. Someone beats him to it when an anonymous letter is sent to the King containing accusations of adultery. Although unconvinced of the rumor, Henry confines Katherine to her apartments pending a thorough investigation.

Lord Hertford’s investigation into allegations of the Queen’s infidelities moves with speed. Deeply upset by revelations of his beloved young wife’s sexual past, Henry weeps. But once adultery is uncovered, his response is swift and decisive.
