Eleanor is taken by her boring husband on a trip to visit their mother in law, who lives in a castle half a days travel by horse. When they're captured by a group of roving knights, her husband Herald makes a bold challenge to the knights - fight him, and if he wins they will kneel for him and pledge service. If he loses, they can have Eleanor.
Before Eleanor has a chance to protest, the challenge is accepted.
What Herald doesn't know is that Eleanor isn't terrified - in fact, she's hoping the knights win.
If they do, they'll take Eleanor rough, unprotected, and right in front of her husband one by one, and Eleanor isn't going to hold back.
