When a spy is fired, they will never receive a "letter of dismissal" from the personnel department, but a "fire warning" that he is not clear about. When Agent Michael Westen (Jeffrey Donovan) was out on a mission, he received a "Burn Notice" and became a forgotten character. Michael did not know what mistake he had made or who he had offended. He returned to his hometown of Miami, determined to find out the truth and ask for an explanation for himself. He can no longer get in touch with his former eyes, and has to avoid the search of the spy network at any time. To this end, he used his spy skills to help the local police solve thorny cases in exchange for their trust, and then took advantage of the police's information to conduct secret personal investigations.
