Zac Power and his family are on another spying mission, on one of the most dangerous islands in the world – Poison Isand.
Zac's mission is to track down an enemy scientist called Dr Drastic, who is believed to be hiding out somewhere on the island. The jungle is full of deadly plants and animals that could be useful in Dr Drastic's evil science experiments.
Zac has only 24 hours to find out where Dr Drastic's hiding, and what he's up to. And his family's life depends on him succeeding!
