She's famous for being a rebel and has a powerful hater: the Roman Catholic Church.

What's the reason? She's an atheist who doesn't have respect for their rules, even when her parents are members of a big part of them, Opus Dei.

The college of cardinals thinks of her as a threat, so with the commander, they decide to show the hellebardiers the temptation that walks in Vatican City.

She meets love in the headquarters of the Swiss Guard, inside of the place she had repulsed since she was younger.

The most loyal man they ever had breaks one of the golden rules, and he does with the infamous girl they warned him about so much, finding himself in love with the danger that she represents.
