The Couple in the Cave:
A couple, lost while hiking — and bickering about it – find shelter in a nearby cave when it begins to rain. Cut to present day: Inside the cave are two skeletons and Booth and Brennan are brought in to determine the cause of death. They team up with a local park ranger who identifies with Booth’s military background, and immediately, they determine that it looks like the two skeletons were locked in a romantic embrace.

This continues over the course of the episode as Booth and Brennan work with the team to solve the case.
