Zsaruvér és Csigavér III.: A szerencse fia.

Five-Fingered Dude is no longer on the force, running a yacht club, when a prostitute is found dead. The case is taken over by Doctor Kardos, eager but clumsy. Meanwhile, a kidnapping case becomes entangled. Doctor Kardos is in charge of the "fight" from the front line, using all "modern" means. The investigation would not succeed without the intervention of Tiny and her little team.
