Neera is plagued by vivid dinosaur nightmares that feel disturbingly real. When she and her young son, Leo, are suddenly pulled back in time to an ancient version of Puerto Rico, those nightmares become a living horror. Dinosaurs roam the land, but they are nothing like the creatures of history. Twisted by genetic mutations, they are faster, smarter, and far more lethal. Stranded in this brutal prehistoric world, Neera must uncover the truth behind the mysterious time shift and the creatures' unnatural evolution. With danger closing in and survival uncertain, her only goal is to protect her son and find a way back to their own time, before this distorted past destroys them both.
