Michael J. Fox reprises his role as New York Citys Deputy Mayor Mike Flaherty, who acts as the slick support system to newly announced Senatorial candidate Mayor Randall Winston (Barry Bostwick). But with a Senate seat on the line and a city to run, Mike is forced to hire a (blonde and beautiful) campaign manager to help lighten the load.
Heather Locklear joins the Spin City cast as sophisticated and sexy campaign manager Catlin Moore who partners up with Mike. Together they become a combustible pairing who for some reason cant seem to get out of each others way. Meanwhile, Mikes staff are forced to adjust to a new kink in the office hierarchy.
While it would not be the last we would see of Mike Flaherty, Season Four would be Michael J. Foxs final season as a Spin City regular and would earn him his career fourth Emmy win for Outstanding Lead Actor in a Comedy Series.
