Cal and Liam search for geothermic sources. There is a major accident which forces Cal to remove his gloves despite the -80° C temperature, but he suffers no frost bite at all. Both are puzzled by this.

Cal, Kurt and Suki go to a remote fishing station to meet Ma Ker and learn more about Cal’s past. Meanwhile, Liam is tortured by Damien when the Pointsmen become suspicious of him.

At the fishing station, Cal, Kurt and Suki are taken hostage by Jonah’s parents who suspect the trio of spying for the Pointsmen. Cal uses his powers to enable the three of them to escape and for the first time his friends start to wonder if there might be something unusual about him.

Suki goes to the underworld and discovers old videotapes in what appears to be a television station vault. She shares her precious discovery with Cal, but he is upset by the risks she continually takes to help him. Frustrated by Cal’s reaction, Suki accepts Damien’s offer of a diner date.

Kurt and Cal go to the underworld, in an attempt to discover more about humanity’s past. While dining with Damien, Suki overhears that Cal and Kurt are in danger. She leaves her date abruptly to go help them.

Later, the three friends screen the tapes and see scenes of beaches and forests and other natural wonders. The images are of such great beauty that the trio realize the earth before the great freeze was not only habitable but a paradise compared to the world they now inhabit.

Cal regains Suki’s trust.

Exploiting Kurt’s relationship with the younger Pointsmen, he and Cal enter the Prison Train. Jonah realizes how much he enjoys his new-found freedom and decides never to return to his village. Everyone tries to convince him otherwise. When his parents are finally released from prison, they blame Cal for their son’s decision.

Liam worries that something may happen to him. Tara assures him that should anything happen to him, she will always be there for Cal. Palidor’s evacuation proposal is passed, but by very slim margin. He orders Damien to find out who his real opponents are.

While a storm rages outsides Grand Star, Liam continues to worry about his son's whereabouts.
