First idea for film

Two cat burglars find themselves on a journey far longer than they expected. After breaking in to a state of the art building with high security they finally get hold of the information they need. However nothing is ever as easy as it seems and the information they're after, held on a memory stick ends up in a pocket of a stranger who has no idea of its significance. After travelling near enough half way around the world to get the memory stick back in their possession the pair fly back to the UK only to find this may not be the information they actually wanted.
