Things get kinky when Booth and Brennan follow murder clues that lead to a lodge used as an S&M retreat for "jockeys" and their "horses." Meanwhile, Angela tries hypnosis in an effort to figure out her elusive husband's name so she can finally divorce him.

Booth and Brennan go to investigate a body found in the Chesapeake Bay. After arriving, they find only the upper torso, giving the team little to work with other than remnants of the victim's breast implants.
