A boy named Theo is called into the house by his father, Venn, whose mother is about to usher in a new life.The family was uneasy, fearing that the upcoming child would be of mixed race.At this moment, Wen En resolutely flew out to seek assistance in delivering the baby, and the camera also shifted to the core character of our story.

At this moment, Japp and Adi Singh are having a fierce confrontation.However, Jep was unfortunately injured, and the other children identified him as Roy's murderer.In the face of public accusations, Singer showed no willingness to seek forgiveness. He firmly believed that his arrival was destiny.He is convinced that he has a mission to lead Gus to Alaska.Gus listened with rapt attention, especially showing keen interest in the cave mentioned by Singer.Apparently, he too had witnessed a vision, but knew that time was running out and they had to move on.

Singer went on to recount his experience, describing the expedition led by Thatcher and his determination to bring back the antidote.At the same time, he also mentioned that Birdie and the scientists at Fort Smith may have inadvertently brought back the pathogen and created the hybrids.Singer was convinced that Gus was the key, because the old adage that kids are the key seemed to be coming true.

However, fate seemed not to favor them.A pack of ferocious wolves suddenly appeared at the door, interrupting their conversation.Faced with this sudden crisis, they must act quickly.Becky quickly gathered her belongings and herded the horses in another direction to distract the wolves.This move gave the team a chance to escape, and they took the opportunity to rush in the opposite direction to avoid being spotted by the wolves.

During their trip, they accidentally stumble upon the house mentioned at the beginning of the episode.At this time, Theo's mother was going through the pain of childbirth.Singh revealed that he was a doctor and could provide necessary help.In return, they get a ride on Venn's plane to Nag Reef.

Meanwhile, Xiana takes over an Alaskan science outpost amid a bitter dispute over energy.However, the pathogen is raging there, and they may not be able to avoid the disaster forever.To make matters worse, she discovers Birdie's snow plow and “Reindeer Man”'s hoof prints.In addition, they also found a body nearby, but it was not Birdie, but someone else.

Back at the house, Singer tried his best to comfort the anxious Wen couple and said many soothing words.Although Wen and his wife weren't necessarily unhappy about having a biracial child, they were concerned about outside perceptions and discrimination against biracial children.During the conversation, Becky sensed that Wen and his family seemed to be hiding something, so she remained vigilant.

Outside the house, Gus and Wendy unexpectedly meet Theo and follow him to his hiding place in the attic.Theo remains wary of the two strangers, but as the conversation progresses, their relationship gradually softens.Meanwhile, Becky discovers a wanted poster for Gus and a radio in a room.Faced with this sudden discovery, Jep decided to take a risk, believing that they would not be in danger under Wen En's surveillance.Despite Becky's concerns, she eventually reluctantly agreed to the decision.

In the attic, a shocking fact is revealed, Theo himself is a mixed race.Just as he was showing off his beautiful wings, a baby's cry came from downstairs - Theo's mother gave birth to a mixed-race child.However, this joyful moment did not bring the expected joy, but instead plunged the two into deep melancholy.In fact, Venn even picks up a knife, and the whole scene seems about to descend into chaos...until Theo rushes downstairs with Gus and Wendy in tow, calming the impending storm with his words.

Although Wen En reluctantly agrees to take them away on a plane, unfortunately, he walks into the radio room and reveals their situation to Zhang and others.As Gus and company rush out of the house, Theo arrives just in time.He quickly drove up to them in a van and urged them to get in and leave.Theo did not leave with them because he needed to take care of his newly born mixed-race brother.Gus and Theo agreed to be friends forever when they parted. Later, after Theo's super hearing gradually recovered, Gus and his companions once again embarked on a journey full of unknowns.

Rossi is gradually approaching the whereabouts of Gus and his party.She was now in Idaho and called Zhang with the disheartening news: She had lost track of Gus and his companions.After putting down the phone, Rossi turned to Venn for help, hoping that he could once again help find Gus and his companions.

At the same time, Birdie woke up from a coma and found himself in a strange church.A suspicious-looking man is walking towards her. He is holding a photo of Gus as a baby and curiously asks about the child's identity.
