The apocalypse came, the apocalypse went, and now there is nothing left but mad robots, madder life forms, and desperate survivors. Self-awareness long since left the bounds of flesh, and the non-human sapients that survived the cataclysm are as lost and desperate as anyone else. One such is Doctor MacIntyre, a self-aware ambulance. This former Lieutenant of the United Bay Autonomies is now a freelance medic offering help to whoever needs it: and he has no shortage of customers. In the violent, desperate world MacIntyre travels through, he can rely on nothing but his wits, his sometimes unwilling allies... and a few missile racks he had installed, just in case. He finds himself battling violent fanatics, would be conquerors of the ruins, and finally, a force that would snuff out any hope of rebuilding a better world.
