The Global Defense Force, or GDF for short, has long had an established connection with another world, Equis, full of anthropomorphic Ponies. But until both governments of Equestria and Earth have a plan to ensure safe passage and policies are in place it is kept top secret on both sides. That is, until a wildfire like no other ravages the Everfree Forest all efforts to contain it have failed, and there is little chance of evacuating everypony in time. Celestia knows they cannot win, in a desperate attempt to save lives she turns to the GDF for their aid.

But will they be able to get the aid of International Rescue in time, or will Ponyville find out what the inside of a blast furnace feels like?

Thunderbirds are GO!
