Patrol seven receives an unusual report. A woman claims that her brother is harassed by his ex-girlfriend. Her brother couldn't come in person because, as the woman claims, he almost had a heart attack and was taken to hospital. The police decide to check all leads and talk to the woman suspected of stalking. This turns out to be a difficult task, because the suspect is undergoing psychiatric treatment herself and avoids direct contact with the police. The suspected woman's brother unexpectedly helps patrol seven in the case. He leads the policemen to an important clue. Meanwhile, the injured person is recovering, thanks to which Assistant Commissioner Bachleda and Staff Aspirant Białach can ask directly about the details of the case. Mikołaj decides to take radical steps to help Ida get out of prison.
