The One Chicago universe has been intact since 2012, and more than a decade later, fans are still clamoring for more stories - despite being inundated with new shows that have similar plots and are in the same genre. Dick Wolf's Chicago Fire started it all in 2012, following firefighters like Taylor Kinney's Kelly Severide as they jumped into action and protected the Windy City from danger. Since its inception, the firefighter TV show has erupted, with series like 9-1-1 and Fire Country all tapping into the same premise.
