The episode is set in Antarctica, 100 million years into the future. The episode focuses on five species: (1) Roachcutter, a descendant of an undisclosed sea bird and one of the first species to colonise Antarctica. It feeds on the insects of the forest and flies incredibly fast and with brilliant agility; (2)Falconfly, a descendant of the wasp which preys on the Roachcutter and other birds; (3) Spitfire Bird, a descendant of an undisclosed sea bird which collects chemicals from flowers of the Spitfire tree which it then spits at enemies such as the Falconfly; (4) Spitfire Beetle, a beetle or mantis that gathers in groups of four to take on the appearance of a Spitfire flower; (5) False Spitfire Bird, an undisclosed sea bird that looks almost identical to the other spitfire bird but cannot fire chemicals. At this point in the future, Antarctica has moved so far north it is now on the equator and has grown a tropical jungle.
