One word, Historical education. Outstanding on that part. A bit too long for a movie. But overall excellent. Great quotes as follows: "You don't need anyone crazy, you're one short step of crazy, what you get", my Riley(Bartha) replies with "obsessed" and Ben(Cage) replies with "PASSIONATE"

Riley replies with "That's where we lost FBI", when Abigail(Kruger) thinks that Ben and Riley are looking at a "Treasure map"
When Ben says "It's invisible" to convince Abigail that the map is real, my baby Riley says That's where we lost Department of Homeland Security"

The film entails Ben(Cage) along with Riley(Bartha) and Abigail who is looking for a Treasure which has been revealed that the treasure found by finding The Declaration of Independence. Initially Ben's Father was leading the search. Ian(Bean) is trying to steal it. It contains a map, an invisible map which leads to a treasure hunt so to speak. So they break into the Museum to steal the Declaration of Independence. In the meantime with no help with the FBI, Ben, Riley and Abigail, get caught in the lurch with Ian and his gang. However Ben turns FBI to his side, so when Ian they are caught breaking into a place, the FBI intercepts and arrests them.

Benjamin Franklin according to film invented the Day Light Savings. Also it indicated the end of World War 2. Something like that.
