The annual TV dance competition 'the red rose', presented by Showbizz Bart, is held in town this year. The commissioner decides to coach Tobi and Mieke, while grandpa counts on his belt-mounted dance coach-invention. Lorenzo and his sister Charlotte want it to be their last, biggest win and he plans to sabotage the other couples by fitting the red roses, which each female participant must wear, with sneezing powder, tranquilizer gas and an electrocution electrode.
Crook brother Freddy and Reddy want to spy on every household to pick victims to rob in their absence. So they 'enlist' gullible commissioner Migrain to distribute free teddy-bears with t-shirts "The police, your best friend" which actually contain mini-cameras. Their first 'safe steal' goes well, but because Toby turned his bear away, Reddy gets caught in the precinct. Now Freddt threatens to detonate the bears by remote.

The commissioner wants the honor, so Toby and Mieke must do all the work under his lazy command. Grandpa Fonkel invents a garbage magnet, but it tends to backfire. Game poacher Stanny Jones, who discovered a near-extinct bird species nest, promises all specimens to a rich taxidermist, but looses the cage during the cleanup.
The town is excited about famous pianist Tkofschip's upcoming recital in the local theater.

To celebrate his sports hero's retirement, the commissioner organized a bike happening where cycling champion Willy Vitesse will receive a golden bicycle. Tow crooks want to steal it.

A crook first distributes free suncream, which turns green when wet, then poses as a professor so he can sell everyone an expensive 'bacteria-cure'. As Tobi an Migrain -who got lost seeking the mountains- spent their holiday at that very lake, they are among the victims. Mieke sees them green trough grandpa's newly invented 'world projector' and gets orders to bring them cash.
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 ...
The vain commissioner entered Toby as 'mere' pilot of his blue police team at a cart race, promising the 100,000 Euros cash price to charity.
