This is an incredibly disturbing episode. Five college student bumble their way into big trouble, as their messing with an Aztec artifact causes the sun to disappear in the sky. Of course, there are all kinds of implications, mainly, the severe temperature drop that affects the entire earth. The problem is that the petroglyphs say that a human sacrifice is necessary to bring back the sun. What do they do. It's the age old story of a group needling to figure who it's going to be. These young actors do a good job with their roles.
