Spike - an undercover secret agent - is dragged from his classroom one ordinary morning to tackle a problem that's getting out of control.

Vegetables are taking over the scientific research institute, and anything that's not a vegetable is considered a weed - that includes the staff of the institute and the prime minister, who is due to make a visit that afternoon.

To add to the problems, rivalries are breaking out between different species of veg.

Can the problem be contained in time? And will Spike survive a confrontation with the Big Pumpkin, the Vegetable Chief?
