Episode 58 of "Lexx"
s04e21 Viva Lexx Vegas

Kai, Xev and Stan stop off in Las Vegas as they wait for a space shuttle that Priest is arranging for them. Without a moth, the shuttle is their only means of returning to the Lexx. They check in at the King Tut, an Egyptian-themed hotel that is run by a group of mobsters. In the hotel room, Stan sees an ad for Slave Girls from the 18th Dynasty on the television and decides to order "room service" for himself. Xev discovers a female wrestling cage match is taking place on the premises and decides to enter, not realizing that it is fixed so that the casino can extort money. When Xev has tremendous success using her Cluster Lizard skills to defeat every opponent, the mobsters start to grow unhappy. They try to persuade Xev to throw the match, but she doesn't understand the concept of losing on purpose. Kai decides to explore the hotel and discovers a rare coffin that he believes belonged to an ancient enemy. He begins to track his foe's whereabouts by following an oily trail that leads away from the coffin. The Slave Girls show up for Stan. They tie him up, take his money and leave him. Meanwhile, there is a killer Mummy on the loose in the hotel that breaks the neck of everyone it encounters. The Mummy enters Stan's room and finds him tied-up on the bed, but Stan is able to escape and rejoin Kai. Kai tells Stan the Mummy is actually a poet-philosopher named Drago that he killed more than 4,000 years ago. Heretics preserved Drago's body and part of his brain in a type of fluid that allows him to function for short periods as a primitive killing machine. Unfortunately, like Kai, Drago is dead and cannot be killed. Kai explains the only way to defeat Drago is to wait until his "fluid" runs out. Kai also mentions that the coffin in which the Mummy was stored bears an inscription, warning people not to open it. With the help of Stan and Xev, Kai is able to trap Drago back in the coffin. They bury the coffin in the desert and head for the space shuttle to return to the Lexx.
