Michael Weston's entire shtick was that he got framed for something, causing him to get stranded in Miami with all his financial resources frozen, his job history non-existent, and all his official contacts and almost all of his unofficial contacts refusing to speak with him.
He winds up doing odd jobs for people who have trouble with criminals, while trying to figure out who framed him, off extremely limited resources. Words and MacGyver-ing are his main tools (alongside cool sunglasses), and all his MacGyver-ing is stuff that actually works IRL and is accompanied by narration explaining how it works, why it's a good idea, or why it's unexpected.
His MacGyver-ing is shit like making a car bullet resistant by cutting open the inside walls of the car to line them with phone books, and countless different ways to turn a cellphone into a wiretap.
