Bones: The Man in the Mud

When a young couple decides to go skinny-dipping in a hot spring, their spontaneity is ruined when they find the remains of a skeleton in the mud. Brennan and Booth soon discover the skeleton is that of Tripp Goddard, a professional motorcycle racer who just won the Super Grand Prix. The team immediately suspects Danny Fitz, the runner-up in the race and Tripp's main rival, to be the murderer. But just when Brennan and Booth think they have it solved, a fiery motorcycle crash claims another victim, and the circumstances seem far from accidental. Meanwhile, Dr. Lance Sweets forces Brennan and Booth to join him on a double-date in an effort to encourage them to interact in a social setting, away from any of their cases.
