Not many kids get to enjoy a Vernian-style adventure once in their lifetime, but in a span of less than five years, Sean Anderson (Josh Hutcherson) gets in on two, thanks to the adventure-seeking members of his father’s family. He is really not enjoying his move to Dayton, Ohio (oops! Since when to palm trees grow in Dayton?) and his mind is preoccupied with finding Jules Verne’s “Mysterious Island”. Considering that this is the kid who travelled from a dead Icelandic volcano to a live one in Italy by trekking and sailing under the earth itself, finding this island might be quite a feat to add to his list. He gets a code from the HAM radio, and he is sure it is his grandfather telling him where the island is. After finding out the code with some help from his stepfather, Hank (Dwayne Johnson), whom was a codebreaker in the Navy, they find the coordinates to the island, which puts it near the island of Palau, and they fear that Grandpa Alexander (Micheal Caine) might be in trouble. Sean gets Hank’s permission to go to Palau and search for the island, so long as Hank goes along with him.
