[3] As described in a film magazine,[4] Manuel La Tessa (Moreno), son of a wealthy South American family, meets Natalie Chester, a young Kentucky woman whose horse has won the race at a South American track.

The offender, whose father is a powerful figure in the country's politics, challenges Manuel to a duel but also hires a man to hide in ambush and kill his opponent.

His mother Donna Isabella La Tassa (Chapman) disapproves of the young American woman and asks her to leave.

Natalie loves Manuel and seeks to uncover the mystery of the bullet fired at him during the duel.

She finally locates the attempted assassin and with numerous bribes gets him to appear against the man who hired him to do it.
