Episode 1
48 mins
The well-known businesswoman Viktoria Fildermann doesn't seem particularly distressed when she reports her husband's disappearance to the Water Police. Jakob, in particular, can't believe the brazenness with which the influential woman repeatedly bluffs the investigators. Her assistant, Klara Bogner, and her lawyer, Dr. Sven Leitmeyer, are at her side. Viktoria Fildermann makes no secret of her contempt for her stepson, Maxim. He only ever saw his father when he needed money for himself and his girlfriend, Thessa. Julia, Jakob, and Paul are puzzled by Nele's hesitant approach to the case. But their boss's thoughts are with her daughter Johanna, who unexpectedly shows up after two years and is clearly carrying a secret that goes beyond her declaration of love for the New Zealander, Josh. It's Mechthild who, with her worldly wisdom, quickly figures it out. Then, completely unexpectedly, someone confesses to the murder of Viktoria's husband.

Jakob loses his temper. He's convinced Klara sacrificed herself for her boss, Viktoria Fildermann. He promises Klara's mother, Theresa Bogner, that he'll find the real culprit and lets himself be carried away with an emotional outburst to the businesswoman. This has dire consequences for Jakob. But these pale in comparison to the bad news that now arrives: a suicide in prison, a murder in Fildermann's villa, and Maxim Gönder and his Thessa fleeing to Switzerland in a stolen boat-until they run out of fuel and are caught by the water police. Then lawyer Leitmeyer shows up at Theresa Bogner's and gives her a concert ticket. Nele can't focus on the investigation because she fears losing her pregnant daughter. Tears flow when she spots Johanna in front of the police station. Johanna has managed to reach her boyfriend, Josh, in New Zealand. But he doesn't react as hoped, while Mechthild wonders whether great-grandmother or Great Grandma will be the better title for her.

The undertakers are astonished. In the middle of Lake Constance, they are ambushed while transporting the body of convict Charlie Maurer. The kidnappers disappear with the coffin and its contents. Jakob and Paul are quite baffled when they later find the boat with the coffin, but without the body. The question that Nele and Julia are also asking themselves: Who would kidnap a dead convict who had no social contacts or relatives? The responsible corrections officer, Franz Kormann, states that he gave Maurer his daily thrombosis injection and found him dead shortly afterward. Social worker Josephine Peschko describes the deceased as a sick, elderly man who had a difficult life and occasionally spoke of a cognac bomber who had crashed into Lake Constance during the final days of the war and was now slumbering there along with 2,000 bottles of the finest cognac. Even Maurer's former cellmate, the Swiss tattoo artist Ludovic Tschanz, who gave the deceased several tattoos during his incarceration, can't offer any further information. When Maurer's body is found in Lake Constance, the case takes a new turn. The autopsy reveals that he died of an overdose of an anesthetic, ruling out natural causes. But the deeper the Water Police dig into this murky case, the more inconsistencies emerge. What role does the enigmatic nurse Ricarda Moniz play? Why did Peschko conceal her relationship to Kormann? Nele solves the puzzle in her own way. When a diving robot is stolen, a race against time begins. A treasure hunter is pursuing murderous goals... It's a good thing that Mechthild reveals the whole truth about the cognac bomber to Nele back home.

During their morning patrol, the Water Police receive a distress call: a body has been found at the beach with an arrow lodged in its chest. The deceased is Jan Kastner, who had been secretly spearfishing near the shore with his friend Tobias Lehner. It quickly becomes clear that the fatal shot wasn't fired from Lehner's spear. Nele and Julia are astonished to find Kastner's wife, Lara, at home. Lara is extremely agitated and refuses to let the officers inside. The widow had been embroiled in a bitter divorce battle with the deceased over custody of their daughter, Mira. Mira has now disappeared. Jakob and Paul discover the little girl hiding near the playground at the beach. Jakob's gentle approach helps Mira begin to trust him. Under Mechthild's care, she paints a mysterious picture. Beach concessionaire Markus Weber informs the Water Police that he has reported Jan Kastner and Tobias Lehner multiple times for repeated illegal spearfishing. But Weber has also appeared in the police files before. And why is little Mira so distant towards her mother? She seems to be the only witness. But she won't speak. By the time Paul and Nele slowly begin to understand, it's almost too late. The police officer who was supposed to protect Mechthild and Mira is incapacitated. A race against time to save Mira's life begins.

Instead of the expected trash on the lakebed, Julia unearths a body during a dive, weighed down with a stone. The deceased is identified as Torsten Engelhard by his coat of arms. When Nele delivers the news of her husband's death to his widow, Patrizia Engelhard, she is already dressed in black. In fact, her husband was buried eight days earlier. The police open the grave. The coffin is empty. Who would steal a dead man from his grave to dump him in Lake Constance? The deceased's son, Lukas, who soon appears at the police station complaining about the police's actions, quickly becomes a suspect himself. His father did not die of natural causes. Torsten Engelhard had made no secret of his dissatisfaction with his unsuccessful son during his lifetime. And now an illegitimate daughter has also come to light: Sophie Polenz found the name of her real father among the papers of her mother, who died six months earlier. And he had apparently intended to make her the heir to the thriving boatyard. That's why Sophie Polenz wanted the body exhumed. Nele is dissatisfied with the progress of the investigation when it turns out that even the priest, Kilian Wiegand, didn't have a good relationship with the deceased, though he did with Sophie Polenz. To make matters worse, Paul now seems to be out of commission. First, he falters at the shooting range, then during a risky chase on the lake, Jakob has to take over his role because a sharp pain incapacitates Paul. Julia finds a strong painkiller in the police station's trash can.

Paul Schott does everything right. With his weapon drawn, he approaches a gas station that has been robbed. Sure enough, a woman emerges from the building and knocks the defenseless Paul to the ground - because he is overcome by a sudden pain. When Julia and Jakob later review the security camera footage, the fugitive, Pia Giroud, has escaped Paul for the second time. Jakob and Julia find themselves torn between Paul, who asks them to keep quiet, and Nele, who is initially only worried about Paul because he has unilaterally returned to duty against medical advice. Pia Giroud is actually serving a four-year prison sentence for stealing medication. She never informed on a possible accomplice and has now used a hospital stay as an opportunity to escape. The Water Police are initially baffled. That is, until they come across a letter from surf instructor Steven Prell, in which he informs his ex-girlfriend Pia that he will soon be getting married. He doesn't reveal his fiancée Kiki Overrath's name in the letter. Nevertheless, she feels very uneasy as long as the escapee is at large. Nele first receives a worried call from Paul's wife, Christina, and then a crucial piece of advice from her mother, Mechthild, on how to deal with Paul, who refuses to admit his weakness and is in grave danger. The doctor overlooked one detail.

Screams alert Nele and Julia aboard the "Bodan" as they pass the Urweltmuseum (Prehistoric Museum) in Bodman. Line Felber is distraught. The daughter of museum director Manfred Felber has just found security guard Tom Geissler - dead under a heavy stone slab, its straps having been deliberately cut, as Nele quickly determines. This is the tragic culmination of numerous attacks on the museum, which Professor Felber suspects are the work of landowner Inge Salzmann. Ever since surveyor and collector Philipp Lux discovered the fossil of a baby besanosaur on her property, the heavily indebted woman has been facing ruin.

Completely penniless, Inge Salzmann has to spend the night on a motorboat. On a friend's boat in the harbor, Nele also finds her colleague Paul, who is on sick leave and suffering from his separation from his wife Christina. Dr. Paul simply refuses to accept Shahyar. Completely distraught, Paul gratefully accepts Nele's offer to move temporarily into the Villa Fehrenbach. There, Mechthild proves to be a wise and helpful companion.
