Traveling dentist O'Connell traverses South America on his motorcycle for the 'Eversmile' foundation of New Jersey, in a fight not only against cavities, but also against fear, ignorance, indifference - and established antediluvian dentists. During a stop at a lonesome garage he meets Estella, who is supposed to marry a few days later. However she'd rather come with him - to meet a former boyfriend in another town, she says. Expecting problems, he refuses to take her, but she tricks him into it and then tries hard to convince him of her qualities and let her stay with him.

Buenos Aires movie director, very fond of the legend of the King of Patagonia and Araucania, decides to make a movie about it.

Neglected by the producer and shortly after by the company, he will make the movie alone, in a surreal landscape like mad.
