I'm hunting for something other than clues for a change: dinosaur bones! Bess, George, and I travel out to the desert to join a paleontology dig. The other volunteers are a pretty quirky bunch, but we're all having a great time...until an important find goes missing. It turns out fossils can be worth millions. I'm making no bones about it - the thief is going down.
