Archeologists captured by the treasure huntress

Somewhere deep in the jungle of Central America. Criminal treasure huntress Evilia Roper has abducted famous archaeologist Prof. Dr. Christina Santa Cordeira and her assistants Dr. Henry George Weaksister and Dr. Diana Henderson from their camp in order to get some clues concerning the hiding place of some pieces of the legendary templar treasure. She has tied up the defenseless explorers and smokes a cigarette to give them a short grace time for reflection:

"You've heard what she said. She...she will do horrible things with us in case we do not cooperate..."
"Yes, be sure she'll find means to make us talk. We...we've to tell her everything we know..."
"The problem is that we don't know anything about the hiding place of the templar treasure. We're absolutely clueless."
"So let's invent something...We've to tell her something, otherwise...I won't like to even think about what she might do with us..."
"You're right. At least we've to win some time..."

Well, seems the unfortunate archeologists are in real trouble...Will they find a way to get out off the clutches of the criminal treasure huntress...?
