Zac Power is on a mission to the world's most dangerous island. He has to track down Dr. Drastic, an evil mad scientist, in a jungle is full of quicksand, piranhas, and poison frogs. No sweat! When you come from a family of spies, you do this sort of thing millions of times before the age of twelve.

But this time is different. Something goes terribly wrong and Zac's geeky older brother gets kidnapped. Now, Zac only has 24 hours to find the formula for solution X and stop Dr. Drastic...before his brother gets fed to a volcano!
