Minature green monsters tear through the small town of Kingston Falls. Hijinks ensue as a mild-mannered bank teller releases these hideous loonies after gaining a new pet and violating two of three simple rules: No water (violated), no food after midnight (violated), and no bright light. Hilarious mayhem and destruction in a town straight out of Norman Rockwell. So, when your washing machine blows up or your TV goes on the fritz, before you call the repair man, turn on all the lights and look under all the beds. 'Cause you never can tell, there just might be a gremlin in your house.
Primatologist Davis Okoye shares an unshakable bond with George, the extraordinarily intelligent gorilla who has been in his care since birth. But a rogue genetic experiment gone awry transforms this gentle ape into a raging monster. As these newly created monsters tear across North America, destroying everything in their path, Okoye fights his way through an ever-changing battlefield, not only to halt a global catastrophe but to save the fearsome creature that was once his friend.
