Up In the Air (Chicago PD)

This story begins almost immediately after the events at the end of 'Taken'.
During a particularly difficult case, a member of Intelligence is in for the shock of a lifetime when someone from the past resurfaces in the most unexpected way. Even worse, it's someone who they'd hoped was gone for good. How will the team navigate their work lives while trying to deal with personal hurdles at the same time?
