Martin wants to catch up on his exams. In order to be admitted as a hardship case, he "borrows" his neighbor's child. His buddy Lars, a successful lawyer, wistfully remembers his old student days and wants to let it rip again before he gets married.

Borchert and Dominique Kuster take over the defense of the taxi driver Jrg Zollinger. Captain Furrer suspects him of the murder of a passenger, the African investigative journalist Nuka Baluba. All the evidence incriminates the uncontrolled suspect, whose testimony initially seems unreliable. Borchert is suspicious of the fact that public prosecutor Dietrich is quick to commit to Zollinger. The "lawyer without a license" suspects that Baluba's research into child labor in cobalt mines in the Congo has something to do with the murder.

Thomas Borchert, the unlicensed lawyer, and his colleague Dominique Kuster take on the case of Anna Sutter, who wants to contest the will of her father, watchmaker Ludwig Sutter, following his unexpected death. Shortly thereafter, Anna Sutter's half-brother René is found murdered in his office, and the young woman becomes a suspect in the murder. The evidence points to her guilt, particularly the fact that her fingerprints are found on the murder weapon and that, according to a witness statement, she was the last person to be with him before his death. Dominique Kuster attempts to represent her as a lawyer in the murder trial and prove her innocence.

Thomas Borchert stands by his conviction as an "unlicensed lawyer" never to neglect humanity when representing a client.

At the opening of photographer Corinna Riemer's exhibition, Borchert finds a dead body outside the door. Suspicion falls on caterer Giovanni Lazzari, who had previously had a heated argument with the murdered art patron Jürg Altweger. Although Borchert does not completely trust Lazzari's assurances, he agrees to defend him at the request of his wife Cristina. Once again, the "unlicensed lawyer's" instincts prove correct: Lazzari not only possesses an illegal weapon, he also harbors another incredible secret. But is he really Altweger's murderer? Together with his boss Dominique, Borchert attempts to unravel the complex case.

Youth psychologist Julia Egger causes a traffic accident, seriously injuring a man, and drives away in panic. Her explanation that she was deliberately forced off the road by an SUV initially sounds unconvincing to Borchert and Dominique, especially since Julia has a history of drunk driving.
