Brennan and Bones are called by Homeland Security to investigate the scene at an old stone house where some glowing bones have been found. Fearing the remains might be radioactive, the pair don protective Hazmat suits and cautiously enter the house, where they find the glowing bones but no radioactivity. Back at the Jeffersonian, the team examines the bones and determines the identity of the victim, but there is no immediate explanation as to why the remains are emitting a green glow. With each of their specialties called upon, the whole Jeffersonian team joins Brennan and Booth in pursuing the murder mystery, which leads them to a group of friends who are shocked to discover that one of their own is the victim. During the course of the investigation, the victim and their friends' MySpace.com pages, along with the photos, videos and blogs they contain, are a virtual tool for the Jeffersonian team's search for answers.
