The party finds itself caught in a massive Nexus storm that almost buries them alive. They come to when a rift opens up and pulls them into Hollywood 1982 (87) when Monster Squad and ET and many other movies are being filmed out of our actual time sequence.
They are invited to Studio 72 by several rad dudes who comment that their makeup is stellar. They eat. They participate in several films until they discovered their wag moved and find a dead security guard.
Madness ensues as the ground becomes foggy and they fight off a horde of zombies. The zombies are revealed to be reprogrammed skelebots as ET slams into the "sky" tearing a hole in the massive building that they are actually in. A mad escape ensues with the group hauling butt out of the building, cavern, and mountain complex.
Surprise! The whole thing was a simulation ran by ARCHIE. ET did shown you how to get home though Rifters.
