The young IT specialist Lukas Wagner (Caspar Schuchmann) is brutally murdered near his sports club for no apparent motive. At his place of work, a Nuremberg freight forwarding company, Lukas was very much appreciated. His boss Weinhardt (Götz Otto) had big plans for him. The world falls apart for Lukas' parents. They investigate on their own, while Lukas' new girlfriend, Mia Bannert (Julie Engelbrecht), is the single mother of a smallDaughter who seems to be keeping a dangerous secret. She's scared to death. But why? The traces of the crime remind Voss (Fabian Hinrichs) and Ringelhahn (Dagmar Manzel) of an unsolved crime. But what does the murder of Lukas Wagner have to do with the case six months ago? The investigators are circling around two cases at the same time and have to keep an eye on Lukas' desperate parents (Valentina Sauca, Karl Markovics).
