Burn Notice: Too Much Back Story?
So here's the tightest synopsis that I can come up with that will make sense.
At least ten years ago, a psych profiler for the NSA named Anson Fullerton got pissed off that there were threats to the world, and to the US, that the president wasn't taking seriously, and that none of the Three Letter Agencies would tackle without authorization. So he set out to use his NSA access to recruit his own private covert ops agency, and he did it in the most evil way possible: by framing America's best spies for horrific crimes and then blackmailing them into working for him. Five years ago, Michael Westen became one of his victims.
Over the course of the first three seasons, Michael pretended to be playing along in order to infiltrate the organization and take it down from within. He found out he was intended to be part of the support team for a sniper that Anson intended to use to bring a corrupt defense contractor to justice, one that was supporting terrorists to gin up business. At the last minute, Michael and another operative took down the CEO and his company legally instead of by killing him. After that, it took him about a year to steal and decrypt a list of every single operative in Anson's organization, and between seasons 4 and 5, with CIA help, Michael took down every single one of them.
Last season, Michael belatedly and too late realized that the head of the organization wasn't on his own employee list. Anson showed up, tricked Michael's girlfriend into thinking she'd blown up the British consulate in Miami killing everybody inside, recorded her confession, and used it to blackmail Michel into helping him rebuild the organization. After one season of this, the things that Michael was going along with sickened even her ... and she's a retired IRA terrorist, bank-robber, and gun-runner. So she cut the Gordian knot by turning herself in to the FBI for the embassy bombing. Even though she now knows that she's innocent, turning herself in was the only way to free Michael from Anson, or so she thinks. So that's where season 6 begins: Anson no longer has leverage over Michael, but Michael has nothing he can use as proof against Anson, either, and Fiona is in jail.
I honestly have no idea if it's going to be any good or not.
