Idiotic movie *spoilers, although there's not much left to spoil*

So they come in and take the old Turin shroud just like that, because it's not closely guarded and kept in an airtight safe, and go to Afganistan, which is also very simple to do, just take a small plane and fly around wherever you want. Then they find the tomb untouched for 500 years but still very visible in the desert of a country that didn't even exist or was known of in Da Vinci's era. I also forgot to mention that the Turin shroud was not a crispy old piece of thin fragile paper but a blanket. Oh, in the end the whole place explodes but they survive because they've covered themselves in the Turin blanket. Oh yea, they found out all that because there are special glasses that show you everything you need to know if you're looking at the blanket. Those glasses were hidden by the villain on the front chair of his car. During the car chase, London is empty. Except for one car, which happened to be the one to kill the bad guy.
