The Cheeseman family is back from back in time. In other words, they're in the present time. Well, presently, at least. They're soon to journey back again — only just a few years this time — to save the life of their beloved mother. But when they get to the not-so-distant-past, they meet something utterly surprising. Something wilder than anything they've seen before — including cowboy poets and good-natured pirates. They are about to meet… The alternate versions of themselves!
