"The new journey begins when...Sean receives a coded distress signal from a mysterious island where no island should exist - a place of strange life forms, mountains of gold, deadly volcanoes, and more than one astonishing secret. Unable to stop him from going, Sean's new stepfather (Dwayne Johnson, Walking Tall) joins the quest. Together with a helicopter pilot (Luis Guzmán, Boogie Nights) and his beautiful, strong-willed daughter (Vanessa Hudgens, Sucker Punch), they set out to find the island, rescue its lone inhabitant (Michael Caine, The Dark Knight), and escape before seismic shockwaves force the island under the sea and bury its treasures forever."
