From Hamburg Harbour to Rotterdam - Tessa topsecret!

Shooting training, karate, heart palpitations and band rehearsals - Tessa Neumann's comfortable life has finally come to an end since she "accidentally" became an agent of the internationally operating secret service R.I.N.G. Now she's out to put a stop to the masterminds of organized crime.

And it’s Tessa's first mission to be involved from the very beginning! Quite stressful but usually absolutely okay, if not now of all times Timo Erhardt, the crush of her sleepless nights, would show interest in her. How can fate throw such lousy timing at her? Actually, Tessa would really like to take a break, but evil never sleeps, as we all know. The scene of the crime in this mission is the port of Hamburg. Here, the customs investigation has uncovered 16 tons of cocaine in the container of a cargo ship. A remarkable catch! But one thing soon becomes clear to Tessa, her band mates and the Mongolian gerbil Hector: the real culprits are not in Hamburg, but in Rotterdam. There a cat-and-mouse game begins, in which the girls have to show what they are made of. With their combined forces, they manage to lure the criminals into a trap so that the Dutch police can arrest them. But mousy Hector discovers that drugs are not the only commodity being smuggled across Europe via Rotterdam: In fact, one of the smugglers is also dealing in exotic animals, animals listed as Endangered Species, so they can't be imported. But be assured, Hector wouldn't be Hector if he didn't do everything he could to save the animals!
