"Why is it always 'why' with you? Grow up already! Not all people are alike. You're good, I'm evil, you're naïve, I know how things are, and you're an idiot while I'm brilliant."
With the jungle and Snitch Gravel left behind, Sam Grant thought the crazier part of life was over and he could now focus on his secret agent training and getting to know his new brothers.
Before he can even get used to safety and comfort, everything goes downhill: his father goes ballistic, his cousin disappears and him and his brothers are called in to rescue a fellow agent from Snitch Gravel's base.
Aside from sending them to battle countless henchmen, the Agency is also keen to keep them in the dark about their most important project - a project Sam and his brothers play a vital part in.
Once again on the road, Sam must figure out how to do something he's never done before: infiltrate Snitch Gravel's base stealthily and come out unscathed.
