It`s the 1920s. Five young student girls from Leiden are on holiday on the Veluwe and hear about a young man of noble title staying in the house next door. When Robbert, the Jonker in question overhears them talking, he decides to pull their collective and shapely legs by pretending to be his own chauffeur. His three best friends are all up for playing along, with the foppish Gerrit-Jan delighted to play the part of Jonker Robbert himself.
