Although Tacoma FD tells the story of the firefighters at Station 24 in Tacoma, Washington, the show is also about family — specifically, the McConky-Penisi Family. The truTV sitcom television series was created by Kevin Heffernan and Steve Lemme (also two of the show's stars) and has lasted for four seasons — it is still waiting for news regarding a possible season 5 renewal. Its humor is pulled from the characters and their relationships with one another, and also the fact that this group of firefighters works in one of the wettest cities in America, meaning that they do not have many fires to fight.
