Season 1Michael is burned and spends his time trying to find out who burned him and why. In the mean time, he takes on a number of local clients just to survive. Michael is helped by his old friend, ex-Navy SEAL Sam Axe and his ex-girlfriend, former IRA terrorist and gun-runner Fiona Glenanne. Also on the roster are Michael's mother and younger brother.
Season 2Michael is now in communication with the people who burned him and working jobs for his handler Carla while trying to stay one step ahead of them with the big picture. He meets a fellow burned spy named Victor who sheds some light on who they are and why he was ultimately burned.
Season 3Michael is out from under the thumb of the organization that burned him, but he's still burned and no longer has the benefits of their resources keeping him hidden from old enemies looking to settle some scores. Michael figures his best shot is to get back in with the CIA, though this leads to him working with a series of very dangerous and unpredictable people like Strickler, Gilroy and Simon.
Season 4Michael is once again working with the people who burned him, this time he is given leeway by "higher-up" leader Vaughn to hunt a common enemy connected with Simon's actions in the finale. This common enemy ends up being the lynch pin of a NOC list that could undermine the entire organization. His investigation ends up compromising the classified data of a counter-intelligence agent named Jesse Porter, who ended up being burned and Michael recruits as part of team Westen but hides his real motivations.

Just as things start to go there way a new party gets involved that sends massive ramifications across the characters.
