An alarm buzzes in a darkened tent. Adriana Chechik turns off the alarm and crawls out of her blankets. Putting on her clothes, she opens the tent and steps outside into the blazing New Mexico sun. Asking herself where Kissa is, she looks around. Her eyes widen when she spots Kissa Sins, wearing tight booty hugging shorts. What is she wearing?!, Adriana asks her. Whatever the fuck she wants, Kissa responds with a mischievous grin. She shouldn't dress provocatively when they're all alone out here in Chaco Canyon National Park, so far away from civilization, Adriana says worriedly. Don't worry, no one's going to mess with them, Kissa tells Adriana, flashing a pistol that she brought with her. But enough chit-chat, Kissa tells her friend gruffly. It's time to go. With a sigh, Adriana shoulders her backpack and they set off down a trail. The ladies hike for what seems like hours through the woods with Kissa in the lead. Adriana, a graduate student at the local university's Department of Archeology, can't wait to reach the unexplored cave that she's there to investigate. Kissa, a tough-as-nails ex-marine, isn't nearly as excited as her friend, complaining that she's just there to babysit Adriana. As they continue on the trail, Kissa can't help but get flirty with Adriana, but Adriana's not into it, reminding her friend that she's married. Their conversation is cut short when they reach a tall face of rock with a small opening that leads up to the cave. Adriana looks up at it, marveling that no one's ever seen it before. Kissa starts the climb up the steep entryway to the cave with Adriana following. It doesn't take long for Adriana to lose sight of Kissa, who dashes up the cliffside. After a long and grueling ascent, Adriana finally reaches the cave. When she turns on her camping lantern, she's shocked to discover that Kissa is standing right next to her. She hands Adriana an arrowhead, telling her she found it while she was waiting.
