Charlie can't wait for school to be over. But he's wondering what particular vacation ordeal his parents have lined up for the family this summer. Canoeing with alligators in Okefenokee? Getting caught in the middle of a revolutionary shootout in Mexico? Or perhaps another trip abroad?

Turns out, this summer the family is staying put, in their hometown. Montreal, Canada. A "staycation," his parents call it. Charlie is doubtful at first but, ever resourceful, decides that there may be adventures and profit to be had in his own neighborhood.

And there are. A campout in the backyard brings him in contact with more than one kind of wildlife, a sudden summer storm floods the expressway, various pet-sitting gigs turn almost-disastrous, and a baseball game goes awry when various intruders storm the infield - from would-be medieval knights and an over-eager ice-cream vendor to a fly-ball-catching Doberman.

Then of course there's looking after his little brother, Max, who is always a catastrophe-in-the-making.
