A man wakes up in an alley, with no memory of who he is or how he got there. He's soon picked up by the police, because they have reason to believe he's one of the people behind PAIRD, Practical Artificial Intelligence Research and Development. PAIRD used to be a government contractor working on autonomous drones; for some reason they suddenly had their funding cut off. Now, PAIRD drones are appearing around the world, causing havoc for no apparent reason. Busted out of the holding facility by another man who also woke up with most of his memory gone, their only lead is a series of enigmatic notes that set them off on an action-filled adventure around the world to find out who they are and just what the heck is going on.
