The gang notice that there's something strange going on in the town - local teenagers have stopped getting drunk, taking drugs or having sex. And it looks like it's all got something to do with a mysterious straight-laced organisation called 'Virtue'. As the gang investigates, they discover that the 'Virtue' movement may not be quite as pure as they make out, and it's left to Nathan to save the day... despite the fact that he's the only one without a super-power.
