Detective Kat Donovan is confronted with her past when she encounters the man she once loved — and learns some news about one she loathes.

After questioning Brendan's attacker, Kat tries again to track down Josh, but instead comes face-to-face with the last person she ever expected to see.

Defying Stagger's direct orders, Kat continues to look into Dana's case — and learns that she might not have known Josh as well as she thought she did.

Kat begs Stagger to help her extract a confession from LeBurne, and Stacey offers to look for Josh. Someone needing help from Kat arrives at the station.

Kat finally gets the answers she's been searching for these last 11 years. Time is running out for Dana, and Titus goes searching for Brendan.
