As part of a covert experiment, the US military deployed a probe designed to prove the existence of a parallel universe hidden from our own. Although the probe successfully entered the alternate universe and reached a planet called Adelpha, its first crucial data transmission is mysteriously cut short.
The probe’s unexpected demise triggers a disastrous chain of events resulting in the creation of a black hole, one that threatens to destroy the Earth. Unless the missing probe can somehow be found and repaired, planet Earth itself is doomed.
