Amidst the desolate pampas of Argentina, two nameless fugitives serendipitously meet and fall deeply in love. The woman, an orphan, is running from her tragic past and sheltered life. The man, a gaucho, is fleeing from the seven vengeful brothers of a man he killed during a fight.

Although both are emotionally wounded and isolated, they become joined by the simple act of cleaning and dressing the deep laceration of the gaucho’s arm. When they discover the ecstasy and contentment of love, their passion is abruptly and violently challenged by the gaucho’s injured arm which becomes infected with tetanus.

The woman faithfully cares for her suffering lover who silently endures the fever, severe muscle spasms, and wasting of tetanus before succumbing to the painful death of lockjaw. Ironically his face is paralyzed with a twisted smile due to the persistent muscle contractions.

The brothers of the man whom the gaucho had killed arrive too late to exact their revenge so they set fire to the couple’s farmhouse and burn it to the ground. The woman places a handful of her lover’s burning ashes in her mouth thus preserving his remains and uniting his spirit with hers forever.
