Burn Notice is a really fun show about Michael Westen, a spy working for an undefined agancy who learns that he has been burned and is now blacklisted and quarantined to Miami. Westen wants more than anything to learn who burned him, but it's not as simple as it sounds. His unknown opponent generally seems content to just keep him stuck in Miami, but as Michael gets closer to the answers he seeks, people occasionally do try to kill him.
That is just the overarching storyline, however. The bulk of the show involves Westen trying to deal with ex-girlfriend and former IRA agent Fiona, old friend Sam (a frequently show-stealing Bruce Campbell who is perfect for the role) and his mother and brother, who, though incredibly annoying to Michael, are trying hard to bring together a sort of family feeling and bring a greater depth to Michael and to the show in general. Each episode involves a story in which Michael is somehow recruited to help someone in trouble. Each of these cases involves the use of Michael's finely-honed espionage skills, which is really great because as he does anything relating to spy tricks-of-the-trade, Michael provides a cheeky voice-over that explains what's going on and gives spy tips. It's a lot of fun, and although the cases are resolved by the end of the episode and could be looked upon as a sort of gimmick, they don't overwhelm Michael's search for who burned him and are in fact quite compelling and unique.
Overall, this succeed as both a great spy show and detective series. Seeing Michael and his pals evade danger and discover the solution to each case is really interesting, making this one of the better shows on television.
