A school field trip gone wrong, two friends, Tommy and Antonio, come across an underground laboratory while exploring and sneaking into the caverns at night. After a bit of scuffle with another intruder, a girl named Maggie, the three activated a portal, which sucked them right in. 

When the trio got out, they found themselves trapped in another world, unlike their own. This strange new world contained much dangerous stuff that they have to be careful of, such as Dinosaurs, elemental hazards, different realms to explore, among other things. 

Tommy, Antonio, and Maggie must work together to try to stay alive. They must find a way out of there as soon as possible. The trio will need to survive the dangers and figure out who to trust in this new world, including each other.
