Cole gets hold of a tape made at the train station when the passengers from the alien-intercepted train arrives. He identifies one of them as Yahir, an aide of Zin's who may have vital knowledge of Zin's plans and the metal triangle Mel's grandmother has. Yahir's body was that of Rudy, a mental patient who has since been taken back to the asylum. Cole poses as a mental patient to reach Rudy and cuts off his dosage so that he can be interrogated about Zin's master plan. Things go amiss when Rudy/Yahir gains his memories back, drugs Cole, and tries to escape with Mel. Cole manages to escape with the aid of his fellow patients, and stops Yahir just in time, capturing his lifeforce before he can gain any information except that the triangle is a key of some sort, capable of letting the prisoners return home.

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.
