Against the backdrop of the brutal medieval war of the Lancaster and York dynasties, known from the history of England as the War of the Roses, a love story and exciting adventures of a young shooter nicknamed Black Arrow develop. Young Cornelius van Berle goes to prison on a false charge of treason. The reason for this is the envy of a certain Mr. Boxtel - after all, Cornelius is close to growing a Black tulip flower and getting the fame and a prize of one hundred thousand florins promised to a successful flower grower.
