(Harry opens the case, presenting it so that Hodgins can see the samples inside; meanwhile, Booth looks like he feels out of place in the lab, surrounded by all this science talk) He was found floating in his dry suit at the top of the shaft. (Zacks gives it to her; Brennan picks up the bone fragment, connects the wire to the hole in the bone and carries it to a desk where she places the bone and wire in a Petri dish and holds a blue light to it - a light, circular mark appears on the bone)
BOOTH: What are you doing? BRENNAN: (head bent over, eyes peering through the lenses of the scope) It's a 300-year-old finger from the left hand of a male. BRENNAN: But Macy is dead. Brennan's right behind him.) But murder! But somebody found out. FRANKEL: Who? HODGINS: Legend is ... Assateague Island is where Blackbeard buried his treasure. Never found their bodies. That's certainly ... that's a good motive for murder. The pirate bones you recovered came from the Jeffersonian to start with. ZACK: In 1832, a team of six men looking for the treasure were killed when a shaft they were digging collapsed. [SCENE_BREAK]

Plan: A: a 300-year-old finger bone; Q: What is a dead body found clutching? A: Booth and Brennan's investigation; Q: Who leads them to a dive site off the coast of Assateague Island? A: a pirate treasure; Q: What is buried at the dive site? A: the lab; Q: Where is Hodgins excited to get out of? A: the bones; Q: What is stolen from the Jeffersonian collection? A: The investigation; Q: What uncovers the possibility that the skeletal remains were placed at the dive site by a surprising culprit with a selfish motivation? A: the suspect; Q: Who is found murdered? A: a new lead; Q: What sends the duo on the search for the owner of the dig shaft? A: the case; Q: Hodgins is excited to get involved in what? A: an underwater death; Q: What do Brennan and Booth race to save Hodgins from? Summary: When a dead body is found clutching a 300-year-old finger bone, Booth and Brennan's investigation leads them to a dive site off the coast of Assateague Island where a pirate treasure may be buried. Hodgins is excited to get out of the lab and participates in a dive that uncovers more skeletal remains, which are authentic but prove that some of the bones found were actually stolen from the Jeffersonian collection. The investigation uncovers the possibility that the skeletal remains were placed at the dive site by a surprising culprit with a selfish motivation. But when the suspect is found murdered, a new lead sends the duo on the search for the owner of the dig shaft. Hodgins, excited to get involved in the case, volunteers for another dive in the shaft, but Brennan and Booth must race to save him from an underwater death when they discover who's behind it all.
