Sucked skyward by the Nile Casino's laser beam and deposited into another dimension, the showgirl Nevada confronts all her mysterious hauntings at once: exploding sheep, a clockwork Neanderthal, depressing songs from the '60s, and a futuristic city with a freakish palace guard. Has she had a mental breakdown? Was it something in the Las Vegas water? Will she escape Caligula's orgy in time for work? Meanwhile, Nevada's disappearance means bad news--sometimes leading to convulsions and death--for some of her friends on Earth.
