Intro. For some time now, a motorcycle gang has been spreading terror in the city and in the country. They call themselves "The Sirens" because they love to chase men, especially if they are virgins, and then leave them naked, tied up and gagged to a lamppost. We don't know why, they do this. For pleasure? Or to find a lover who will be able to satisfy them?

The Sirens, a group of psycho biker women?
