One quiet, moonlit night, two girls run away from a remote castle. They are terribly scared: they have never been anywhere but in that far-off place and, what's more, the night hides fatal specific dangers for them. So, why have they decided to risk it all... and why now? They both have secrets, but the younger girl in blue can't even imagine how many mysteries her sister in red - doomed to always dress in red - could unveil for her. Ironic destiny will put them in the way of two young men, who will eventually prove to have their own good reasons to join in the fight they have, almost inadvertently, begun with their escape.
