It is about a spy who is sort of excommunicated (or given a "burn notice") from the spy world, and he is stuck in Miami trying to discover why it was put on him, and who did it, and to make money to help he takes on detective-type work for victims of scams etc.
It is a real black comedy, really off-beat. There is a lot of action, but it's not really heavy or anything. I definitely wouldn't say there's too much comedy. I would recommend checking it out!
