When a bizarre green storm drags rugged trucker Sam and six college students into an alien realm, they are plunged into a nightmare ruled by giant insects and thirty-meter-tall man-eating giants. Their professor, Hale, is devoured the moment they arrive.
Sam steps up as the protector of these young survivors—but the foreign world begins to alter him, granting him superhuman strength and hyper-healing, while slowly mutating him into the next giant. Is he their savior, or a monster in the making? The terrifying question tears the group apart.
In the end, Sam masters the supernatural force, pulls their professor out from inside the giant, and sacrifices his divine powers to become human once more, leading everyone back home. Yet, a faint ember of light glowing beneath his skin serves as a chilling warning: the otherworldly realm is already choosing its next host.
