In this follow-up to the 2008 worldwide hit “Journey to the Center of the Earth,” the new family adventure “Journey 2: The Mysterious Island” begins when 17-year-old Sean Anderson (Josh Hutcherson, reprising his role from the first film) receives a coded distress signal from a mysterious island where no island should exist. It’s a place of stunning beauty, strange life forms, mountains of gold, deadly volcanoes, and more than one astonishing secret. Unable to stop him from tracking the signal to its source, Sean’s new stepfather, Hank (Dwayne Johnson), joins the quest that will take them first to the South Pacific, and then to a place few people have ever seen. Together with a helicopter pilot (Luiz Guzman) and his beautiful, strong-willed daughter (Vanessa Hudgens), they set out to find the island, rescue its lone inhabitant and escape before seismic shockwaves force the island under the sea and bury its treasures forever.
