At a cosplay party, the young Bea "Akanamo" Pscheider is murdered. Pursued by a "white magician", she tried to flee through the dark forest, but soon succumbs to her stab wounds. The party organizer is the designer Johnny Lehmann, who is also the father of Bea's best friend Silke, also a cosplayer. The investigations are therefore focusing on the cosplay scene, including the shy Leon Hofstätter, who had contact with the victim online as Prince "Hirakimo". With Bea's parents, the SOKO then comes across clothing designs that could be interesting for several suspects.
