You want to watch Chicago Fire online. We know this because here you are, on the watch Chicago Fire online page. So what brings you? Is it the many tweets you see each week talking about how fanastic an episode was and you're wondering where you've been? Is it the hottie mc hottersons that make up the cast (some are not good looking, granted, but they're all beautiful on the inside!) or perhaps you watch Chicago P.D. and realized, HEY I don't know what they're talking about. I wonder if I looked into this Chicago Fire show if I'd get a better understanding of the characters here on the other show. You're right. Watching both is best. But if you want to start at the beginning, starting with Chicago Fire Season 1 is the place to go. So what are you waiting for?
