But first they'll need to steal Goya's Saturn Devouring his Son , because he hid a clue in it about the secret location of Magellan's sextant, but the clue can only be discovered through the use of a magnetic resonance imaging, which Da Vinci invented while on vacation in Crete.  So they're forced to enter a nearby spanish hospital dressed as medicos, hoping to find an MRI machine big enough to accomodate the painting.  

Of course, hilarity ensues when the three chipmunks are mistaken as real surgeons and have to perform an emergency atrial fibrillation on the President of Europe, who is visiting Madrid from Europe City, the capital.  See it's hilarious because they're not really doctors, and they don't speak Spanish, and the President of Europe is super important and wears a monocle and has a billowy mustache and an accent of indistinguishable origin.   Oh, and also because nobody notices that they're squirrels.

After they've saved the President's life through a series of madcap coincidences, (they confuse the word "see" with the spanish word "si", for example), they find the location of the buried sextant on Mactau Island, underneath an old abandoned church.  Upon retreiving the sextant, they realize that it is more than a navigational device:  it acts as a cypher needed to translate the Dead Sea Scrolls, which they'll discover contains a hidden message describing the location of Moses's tomb, which was where 2nd century pirates hid millions of dollars worth of... well, I don't want to ruin the ending for you, but let's just say things turned out pretty "golden" for our furry little friends.  Let's also say, they'll never have to worry about finding money to buy "golden grahams" again.      

Oh, and I also don't want to spoil whether or not the nerdy squirrel, Arvid, is finally able to draw up the courage to ask out Tatyana, the beautiful Russian heiress who dropped out of the world of modelling to pursue her dream of being a cartographer, and with whom he's harboured a secret crush that was evident to everyone but to Tatyana herself, who has also just discovered that Nikos, her seemingly perfect Greek fiance, Formula One Champion and millionaire playboy, was all wrong for her because he didn't understand her career, acted rudely to a waiter in scene four, and whom she found out was secretly trying to undermine the squirrels' efforts to find Magellan's sextant.    

And I definitely don't want to share where the whole group ended up and how many pina coladas the fat squirrel orders from the beachside cabana boy.  Cuz who even says the end up at a beach?  Those cabana boys could be anywhere.

..

Anyway, when do I get my million dollars for this?

thats why they show the whole movie in the preview these days...thru ingenious marketing (a la the McDonald Effect)...they found that people want to know what they are buying before they buy it
