How Cage figures the clue that leads him there is pretty far-fetched but its the key to the story. The clue is finally determined to be on the back of the Declaration of Independence. Cage must solve riddle after riddle to find the ultimate clue to the treasure's whereabouts. The basic story has been reviewed several times, but it's the continuation of a 200 year old treasure hunt. There's actually not very much actual violence (strange for a Cage film!), but the story is so well-written that even Cage can pull it off without any gore.
There is enough action and suspense to keep the viewer's interest and also to maintain the pace of the film. I am NOT, repeat, NOT, a Nicolas Cage fan, mainly because he relies too much on action to carry his films (instead of his acting), but this is a pretty decent flick.
