YMMV / The Outer Limits 1995 S 5 E 22 Better Luck Next Time

• Complete Monster: Two Energy Beings have been living on Earth for centuries, stealing host bodies and using them to commit murder after murder for amusement and to alleviate boredom; Ripper one of said energy beings was Jack the Ripper himself. Detectives Terri and Girard end up each working with an alien, both claiming they are officers sent to hunt down the killer. At the end, the truth is revealed: the two are partners in crime and have been playing the officers for fun with the only excuse being how bored they are as immortals. The two have been spending centuries playing their games and corrupting good people into killing their friends and partners out of paranoia; they plan to hijack Terri's body after she mortally wounds Girard and use her police connections to have even more fun. When Terri and her dying partner mortally wound both killers' host bodies, Terri opts to kill herself to prevent them from stealing her body, knowing they can't survive long without hosts and unwilling to allow them to continue their rampage.
