Allmen und das Geheimnis des koi

Johann Friedrich von Allmen (Heino Ferch), a self-proclaimed detective and specialist in stolen artworks, but above all a Swiss bon vivant, flies to Tenerife to meet his extremely wealthy girlfriend Jojo (Andrea Osvárt). But instead of planned romantic holidays, shortly after his arrival, he stumbles upon another case. This time, however, not entirely voluntarily, as he is blackmailed by the infamous film producer Steve Garretta (Uwe Kockisch) to find his missing and million-dollar koi carp. This is no easy task for Allmen and his loyal servant Carlos (Samuel Finzi): Soon they are facing a murder and further blackmail, and then Jojo appears, who shouldn't know anything about the investigation and suddenly is more involved than Allmen would like.
