In Hamburg's fourteenth precinct, a new colleague joins the police force and a new case is presented: a mysterious accident at a construction site.

Ben notices a few odd circumstances surrounding the death of Jannik Sternberg, while the cops at the station continue to try to impress Nicole, their new colleague.

Too many things about Jannik Sternberg's death seem odd, especially when the colleagues find out that this isn't the first "accident" at the construction site.

In this episode, the police find more evidence that Jannik's brother-in-law, Mr. Nagel, may have been involved with his death.

The officers investigate an unlikely break-in as the case of Jannik Sternberg becomes increasingly more suspicious.

The construction site where Jannik Sternberg fell to his death comes under scrutiny. At the station, Dirk and Lothar realize that Nicki might need a bit more supervision.

Jannik Sternberg's boss offers his widow a payoff, and in return his widow offers the police evidence of Sternberg's apparent suicide.

The colleagues are still having trouble believing that Jannik Sternberg would have committed suicide and are becoming increasingly frustrated. Meanwhile, the ladies from the crime prevention seminar seem to have taken matters into their own hands!

The pills found at the construction aren't antidepressants after all, which contradicts Ms. Sternberg's account of her husband's state of mind! Then her distraught daughter suddenly disappears.

Despite Olaf's worries, Marie is found, and the other loose ends are tied up as well in the conclusion of this episode.
