After agreeing to come to Pasadena, Doug meets with Rachel and the team to tell them of the encounter. He meets Rick Ross, Rachel’s current boyfriend and a member of the Caltech team. The two instantly become adversaries and rivals as Doug’s feelings for Rachel are reawakened.
Doug realizes the team has built a craft to take them down the portal and to the center of the earth. A heated discussion at Rachel’s apartment leads to a fight between Rick and Doug. Rick’s hand is badly injured. Doug then learns that Rick was to pilot the craft.
The Caltech team realizes the only way to continue the mission is to replace Rick with Doug Ramsey. Though some are torn about the decision they move forward as Doug accepts the challenge.
With Doug at the helm, they launch the Palindrome – a ship designed through a joint effort between Caltech and JPL using the latest in nuclear technology. Traveling to the center of the earth they find more than UFOs. But when they try to leave to bring the news back to the surface, they learn it was only ever to be a one way ticket. Luckily, they have Doug Ramsey with them. Doug always has to have his way, and he wants home.
