When a spy is fired, they will never receive a "letter of dismissal" from the personnel department, but a "fire warning" that even they themselves are not very clear about... When agent Michael Westen (Jeffrey Donovan) was on a mission outside, he received a "Burn Notice" and became a forgotten character. Michael didn't know what mistake he made or who he offended. He returned to his hometown of Miami, determined to find out the truth and seek justice for himself. He could no longer contact the former informants and had to hide from the search of the spy network at any time. To this end, he used his agent skills to help the local police solve difficult cases in exchange for their trust, and then used the police's information advantage to secretly conduct personal investigations.
