"They were like, these criminals that helped track down that evil dude with the secret organization...And they fought robots and evil A.I.s and bounty hunters, and there was that one big guy who was like RAAAAA and they threw him off a cliff and one of them died a bunch, and another guy that was bad, then good and oh, there were ghosts! But..uh..after all that they were like, pardoned and stuff."
