Hai-Alarm am Müggelsee (2013)

During the morning water-temperature check, the right hand of the lifeguard at Friedrichshagen lido is mysteriously bitten off. The bite marks suggest that a shark is living in Lake Müggelsee. At the same time, shark hunter Snake Müller returns to his hometown of Friedrichshagen from Hawaii aboard his houseboat. He soon realizes that there really is a dangerous shark in the lake. The mayor consults his experts about the seriousness of the situation and initially plays down the danger. But concern among the population keeps growing. On the advice of city-marketing officer Vera Baum, a shark alert is eventually declared. Lake Müggelsee is closed to the public, and to distract the people of Friedrichshagen, the annual Bölschefest—a popular street festival with a long tradition—is simply extended indefinitely. Before long, however, the residents have had enough of the shark alert and loudly demonstrate, demanding that it be ended. In the end, the shark is to be driven out of Lake Müggelsee by releasing large quantities of beer from the Berliner Bürgerbräu brewery into the lake. After the beer is poured in, Snake Müller and his ex-wife use his boat to lead the shark away from Lake Müggelsee.
