When Judo Girl goes missing, Atlas goes to Isis for help, but what they will find suggests that their friend has already fallen at the hands of an international crime syndicate known as the Under-worlders. And if Isis and Atlas can’t get their act together and work as a team, they too might fall victim to the evil syndicate.
