Aaron is back in the GM chair as he takes the RPPR crew through the dark tunnels under New York City! A community of homeless citizens have banded together in an abandoned section of the NYC subway system. They are protected by a mysterious cult of silver-masked acolytes who claim the dead for their own, but otherwise ensure that the homeless remain safe. But when an unnatural danger attacks the community and threatens everyone, several members of the community rise up to put a stop to it. They have little but their own lives to risk, but they won't stop them from finding out what lurks in the dark heart of the city.
