- A hitman with a flawless record who gave himself up for unknown reasons after his last kill (you know, the sleek, always-wears-a-suit type).
- A mob leader (of the rough, slightly comedic relief-y, violent but also well-connected with the underground type).
- A young genius psychopath serial killer (of the absurdly high IQ, multiple PhDs, killed a bunch of people type).
Needless to say, the plot's probably going to thicken. There's only one season of eleven episodes, and, as you can see, it's pretty much by the numbers, but the first episode was entertaining enough, so it might end up being a once-a-week shut-my-brain-off thing.
