 A city dweller, out for an evening stroll, hears a woman s cries for help and rescues her from an assailant who is trying to drown her in a public fountain. However, when our mild-mannered hero pulls her from the water, she proves to be not a woman but a harpy - with a woman s face and breasts and the body of bird of prey. He takes her home and treats her like a human, but she is true to her nature, mercilessly and ravenously taking command of the household, dispatching his pet, and trying to make sure he can t leave. When he does manage, by a clever ruse, to get out of the flat and enjoy a snack, things don t go as he d hoped.
