Seven year old Marietje loves her island home, Schokland, where she lives with her parents and brother. The island is under constant threat from the surrounding Zuider Sea. When a storm takes Marietje, she insists on returning and agrees to come back and watch over the island. As the Spirit of Schokland, Marietje watches as the island is abandoned and ultimately reclaimed from the sea as part of a large polder in the Netherlands. Based on historical facts, this is a tale of love and perseverance in the face of adversity. Schokland is now a UNESCO World Heritage Site.
