The commissioner and Tobi are ready for the annual police fitness test in the village, presided over by chief commissioner Manz. Mieke is preoccupied with a millionaire and his spoiled-rotten younger partner, who want to buy the sea-life show's dolphins for her birthday. As their attendant Jos suspected, after traces from a first attempt warded off by the seal, the couple hires two brother, wanted crooks, to steal the 'fish'. Mieke is late for the test, disqualified and fired, unlike the commissioner, who cheats by shortcut as usual. Mieke's replacement is an undercover inspector.
