Tina, a general slavey at the Red Mill Inn suffers under the extreme temper of her employer, Willem.  She falls in love with Dennis, a visitor to the Netherlands.  Gretchen, the burgomaster's daughter, is betrothed to the elderly governor, though she is actually in love with Captain Edam.

Tina masquerades as Gretchen in order to prevent the forced marriage; when she is locked in a haunted mill, she is rescued by Dennis.
