In the small Frisian town of Lenten, twin brothers Hielke and Sitse, the mischievous sons of blacksmith Klinkhamer, bring entertainment to the community with their pranks, often targeting the town's gullible resident Gerbert. Their mother is mortified by their antics, while their father secretly admires their bravery, honesty, and cleverness. When the town is targeted by two city slickers, the Klinkhamer twins team up with their father to rescue the doctor, earning them a wrecked car as a reward. They use the car to fix a boat, which they had damaged earlier, and then get involved in the town's "olympics" held by a group of posh university students from Leiden. The event features a swimming race, where the cheaters and bullies receive their comeuppance.
