For a long time, the three sisters Joanne, Kira and Thalia were on their own, living their separate lives. They believed their mother Arianna, the Queen of Thieves, to be dead, executed twenty years ago in the town of Ahkra by the villainous Lord Raul Capello. One day, their father Lysander calls them to Ahkra. He has big news: their mother, and his wife, could still be alive! At least, that's what a mysterious figure is telling him. They seem to be the only one who knows what's really going on, and they’re willing to help the sisters, for a price. They'll need to follow in their mother's footsteps, robbing from the rich to meet the increasingly outrageous demands of their mysterious benefactor.
