Description: 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 LED 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. Adriana is excited since it looks like a Mayan arrowhead and Kissa tells her that she can show her where she found it. Kissa takes Adriana deeper into the cave, bringing her to where she found the arrowhead. Eager to see what other secrets are buried there, Adriana gets down on her knees, sifting through the dirt of the cave floor. A moment later, Adriana is elated to find another arrowhead and snaps a photo of it. When she takes a look at the photo, she notices something in it, something strange, a shiny object protruding from the ground.

Overcome with curiosity, Adriana grabs a small folding shovel out of her pack and starts digging feverishly, asking Kissa to hold the lantern as she pulls the mysterious object out of the dirt. It's a hunk of smoky quartz crystal about the size of a human fist. It almost seems like it's been carved into a shape. Adriana takes a plastic water bottle out of her backpack and washes off the hunk of quartz to reveal that it has been carved into the shape of a human skull.

Adriana is in awe, saying that it could be hundreds of years old...or thousands. OR...it could have been carved last week, Kissa points out. Adriana retorts that that's unlikely since there are signs of extreme weathering on the surface, indicating that whatever carved it did so quite a while ago. Pulling the lantern close, Adriana examines the crystal skull closely. Adriana's eyes go wide with wonder as a light suddenly begins to emanate from the skull, growing ever brighter. As Kissa looks on, Adriana is transfixed as the glow from the skull gets brighter and brighter, reflecting in Adriana's eyes. Suddenly, Kissa's voice cuts into Adriana's trance, asking her if she's okay? Adriana shakes her head back to reality, blinking in confusion. She takes a breath, saying that they'd better get back to the camp.

Later, back in their tent, Kissa dozes off while Adriana investigates the skull more, peering at it closely with a flashlight. Suddenly it begins to glow again and Adriana locks with the skull as the light increases in intensity. This mysterious glow flashes in Adriana's eyes and a strange energy seems to take hold of her. Abruptly, she rouses Kissa. What's wrong?, Kissa asks, groggy. With a seductive smile, Adriana tells her friend that she wants to fuck her. Kissa is shocked since this isn't like Adriana at all. What's come over her? But Kissa's surprise soon turns to lust as the impossible-to-resist Adriana kisses Kissa softly, pulling the blankets away from her. They dive into each other, stripping their clothes off and instantaneously losing themselves in each other's supple bodies.

But the adventure is only just beginning for these amateur archaeologists. Are they prepared for what awaits them when they uncover the sapphic curse of the crystal skull?
