A team of researchers and observers are plunged into a terrifying alternate dimension filled with horrendous creatures when a demonstration by a respected physicist goes horribly awry. The device was supposed to allow humans to gain a glimpse into the hidden worlds all around us. But when it malfunctions, the survivors of the incident go where no human before them ever has. Now, in order to get back to where they belong, they must avoid becoming prey to the creatures that are eager to get their first taste of human flesh.
