Season 1

No one on the force knows why Detective Sunny Becker was on leave for 6 weeks. Upon her return she's immediately assigned a dangerous case-track down a known serial killer who has escaped prison before he kills again.

Serial murderer, Haffner always seems to be one step ahead of police, causing suspicions for Becker that there's a possible leak amongst the squad. The hunt for the killer becomes more personal for Becker.

Becker's hunt for the killer becomes more complicated. Becker's suspicion that there's a mole on the squad grows as she becomes paranoid that the mysterious figure helping Haffner wants to sabotage her career in the process.

The internal corruption that's been helping the killer continue on the lam is not really revealed. Becker risks everything to protect the killer's illegitimate teenage son from danger as she concocts a plan to lure Haffner out of hiding.

The killer attempts to extort funds from his son's mother in order to sustain his life on the lam. With morale at an all time low the squad makes one more push to bring Haffner in.

Becker discovers who is trying to sabotage her life and career. As she tries to wrap her head around it, the rest of the squad searches for the killer's son. But are they heading toward a dangerous trap?
