It's no secret. The tale at the heart of the Assassin's Creed series is about as ridiculous as they come. But Ubisoft have done a pretty damn good job of condensing the last three games' narratives into a two and a half minute synopsis for those new to the franchise. Hell, even if you're a veteran, you'll probably get a nice little recap kick out of this one - explaining the inexplicable in relatively simple terms. If you find yourself scratching your head at the end of it, though, don't worry; it proves you're sane.
