Meteorologist Jan Becker has lived in America for a long time to study tornadoes and suspects something terrible when he returns: the extreme weather conditions in Germany - heat and hailstorms in a confined space - have the potential to spawn a huge tornado. But no one believes him, especially not his father, the head of the weather service. When a supercell forms a short time later in the Berlin area, Jan immediately sets off to gather evidence for his theory.

SOKO Leipzig is a German police procedural television programme, a spin-off of the earlier German police programme SOKO 5113. It was first broadcast on 31 January 2001, on German television channel ZDF. On 12 November 2008, the first part of a two-part crossover between SOKO Leipzig and British police procedural The Bill was aired, with the same version being shown on both ZDF and British television channel ITV1.
