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.
