A group of ruthless pirates attack a seventeenth century Huguenot settlement on the Isle of Devon in search of treasure and will stop at nothing to obtain it.

In a village of Huguenot refugees, Jonathon Standing is exiled by his father to a nearby penal colony for his improper relationship with a married woman. This penal colony is then invaded by pirates who force Jonathan to lead them back to his village, convinced that it contains a great treasure.—dinky-4 of Minneapolis
