The 21st Century is a world without war. But not without killing.

The Big Hunt, "a safety valve for humanity's latent aggressive in-stincts," pits licensed international citizens of the future against each other in a vicious but legal duel of death.

At a Pop Art exhibit in New York, beautiful "victim" Catherine Meredith (Ursula Andress) guns down her Oriental opponent with a metal, rapid-fire brassiere.

At a Grand Prix House Show in Rome, "hunter" Marcello Polletti (Marcello Mastroianni) blasts his "victim" with dynamite-spiked spurs.

Now the lots are drawn again, and it's Ursula vs. Marcello. For one, the fame and money of ten kills... for the other, a surprise ending.

Which will be The 10th Victim?
