It's 10:30 A.M. Local time. Reporter: Al and Christine travel from Michigan to Utah, and then make the long journey over rough roads, tracing their son Josh's path into the western desert. I can't imagine what Josh was thinking the day he came out here. Yeah. Reporter: Josh has been unplugged for more than seven weeks. They can't wait to see him, but first they have to find him. Josh is somewhere out here, and you guys are going to signal for Josh using this. Okay. Reporter: Wyatt, a field staffer, gives them a wooden device called a bull roar used in ancient rituals to send signals over long distances. They stop and listen for a response from Josh. But nothing. Off in another part of the desert -- Oh, come on. Reporter: Josh is having trouble. Swear to god it was working. I know. It was working yesterday. Reporter: It's not a bad metaphor for the family's communication problems. When Josh would shut himself away in his bedroom, gaming all night. It's 3:00 in the morning. It's time to get off now. Reporter: Christina takes a turn. And at last, Josh responds. Was that it? That was it. That was it. That was it right there. Okay. Reporter: Moments later, after the longest and most difficult separation of his young life, 54 days apart. There he is. Is he there? Oh, there he is. Hey Josh, how are you? Good. Good to see you.
