Viktor Tourjansky ("a film by" in Italian credits / "Directed by" on American posters)
Giorgio Rivalta ("Director of Italian version" in Italian credits)
(IMDb lists Fernando Cerchio as director along with Tourjansky, with no mention of Rivalta - I have no idea why)
Iride, live-in "model" of Greek sculptor Praxiteles, finds Macedonian soldier Laertes unconscious on the beach. She takes him home where she cares for him and hides him from the Greek soldiers who are searching for him. Iride and Laertes naturally fall for each other, but when Laertes kills a soldier, jealous Praxiteles betrays him. Iride leaves, preferring life as a prostitute, but she is saved just in time when Laertes leads a Macedonian invasion.
