Isn't everyone a little wild? Miles and Niles, the undisputed masters of pranks, are on summer vacation! Free from all school obligations, the two tricksters are now fully enjoying the sweet wild life, conquering the forests outside Yawnee Valley, climbing trees, exploring caves, and - yes - coming up with highly creative new pranks.

And this year, he has found a few admirers. When Josh and his bragging cadets decide to bully Miles and Niles, it will be revealed what is stronger at the end of the day: the power of clenched fists or the flashes of genius from an unleashed trickster duo?.
