Greg Masterson, a brilliant engineer and self-made billionaire, is the brains behind Earthport One, with the space station serving as the first stop for commercial space tourism. Straker and Foster are given a tour by Masterson under the guise of a film studio, but the fact that some places are restricted and off-limits raises concerns. Straker calls the military, who confirms their involvement in the scheme by their evasiveness. Interceptors detect three UFOs, two of which are destroyed. Before the Interceptors do the job, the third makes his way to Earthport One and is shot at by hidden missiles from the station.
