After a journalist is killed in his own car, Ola's team looks into what he was investigating to uncover why he was targeted.

What appears to be a couple dying in a suicide pact ends up being more complicated, and Michał asks Ola for help as Regina uses herself as bait.

Someone sends the Violets a video of a young man who ends up beaten in a cemetery just as the police respond to a call about a victim at a hospital.

The Violets investigate a closed case after receiving a letter asking for assistance getting a convicted felon exonerated.

The police face criticism for working with the Violets after a new murder -- and a serial killer on the loose -- complicate the Hycel case.
