One of the prisoners, a Desserian named Suudor, is duplicating famous serial killers like Gacy, Manson, and the Boston Strangler. Tracking him, Mel and Cole find he's taken a ticket to England. Coincidentally, Jess is in England with her ex-boyfriend. Suudor is planning to duplicate the acts of the most famous serial killer of all time: Jack the Ripper. Worse, one of Zin's operatives is helping Suudor and gives him pictures of Jess and Mel. Suudor escapes Cole at a hospital and prepares to close in on the women... (to be continued...)

Mel tries to dissuade Jess from meeting with Hunin in Whitechapel to get engaged, but oversleeps. Meanwhile Cole tries to track Suudor and runs afoul of Jager, one of a set of bonded Orsians. He defeats Jager but alerts Parker, his twin-Orsian. Suudor tries to kill Mel and Cole catches up to him but is flash-frozen by Parker. It was a trap to lure Cole in. Suudor goes to kill Mel but Cole manges to recover enough to freeze time, rescue her, capture Suudor, and escape. It turns out Parker and Jager were not any of the escaped prisoners and that Zin already had an organization on Earth prior to the escape. And that Zin had some reason to lure Cole out of Chicago and to London...

After bringing in another escapee after some tests, Cole determines a way to zap all of the remaining prisoners off Earth and back to Sartop at the same time by remote. However, one of the currently held lifeforces is contaminating the process, and he and Mel desperately try to determine which one before the wormhole closes. Things get complicated when Cole is zapped by an energy burst and loses his memory. He gets it back with some prodding from Mel, and they identify the ""contaminated"" lifeforce just in time and get rid of every remaining prisoner on Earth. Cole goes back, his mission completed. But then he returns, realizing his home is on Earth with Mel. But as they celebrate, we see the display screen show all the fugitive prisoners reappearing all over the U.S.
