Zak visits his grandfather, and accidentally activates his experimental shrinkinator, before waking up in a whole "new" world.

Zak trains to become an Insectible, and sets out on his first hunt for a missing Shrinkinator part, only to fall for Adilla's trap.

The Insectibles investigate the possible existence of a headless zombie, causing chaos at every turn.

Joined by a group of genetically modified insects, Zak and friends use their superpowers to solve everyday insect mysteries.

When Zak is told he is to spend the summer with his grandfather instead of at football camp, he does not expect to have the fate of the world resting in his hands.

Willow and Grandpa try to recover a piece of the shrinkinator that got stuck in a wall, but when they remove it the wall begins to crumble.
