Meanwhile, a random arrest at 15 Division puts Swarek and our officers in the middle of a messy, violent Drug Squad investigationthe same investigation that’s being fueled by Andy and Nick’s undercover intelligence. Once the dust has settled from the aftermath of the bust, Andy steps back inside 15 Division for the first time in 6 months. Reunited with her friends, and home at last - it isn’t long before she realises life has carried on without her at the station.
