On an island beach a woman vows to avenge her brother's death at the hands of a pirate leader. With help, the woman spies on the pirates and then gets a job as bodyguard to the pirate leader.

After her brother was killed by a notorious all-female pirate gang, Morag dedicates her life to bringing the murderers to justice. Soon, she has become an important member of the pirate gang and has begun acquiring the loyalty of key members. Eventually, she makes her move and challenges the leader, a demi-god (literally), known as "The Daughter of the Sun." The story of Noroit is inspired by an early 17th-century tragedy by Cyril Tourneur, and, though it is only the third one filmed, the movie is the concluding episode in a four-part series by director Jacques Rivette.—Clarke Fountain
