The first - and perhaps last - mission! Finally, the ultimate sexual weapon appears to the women of earth!

Coincidentally, at the same time that a mysterious meteorite drops from space, murder cases begin to break out all over Japan. The victims are only women. All of the dead bodies have holes in them, are bloodied, and contain alien semen.

The government devises a plan of operation they call 'The Artificial Hormone Scatter.' They use passion filled hormones to lure the monster into a trap and destroy him. Then the biggest group-sexcapade in history begins!

As this continues, the monster becomes more powerful than ever. The people believe that this might be the end of the earth. But, at that moment, a giant Venus comes to the rescue!
