A seagull is caught by the black tide of a sinking petrol ship. She manages to fly inland and falls down in a garden by a cat. Moribund, she asks the cat to fulfill three promises: that when she lays her egg he must not eat it; that he must take care of it until it hatches; that he would teach the newborn how to fly.

A fragmented biography, inconclusive, partial, of the brilliant Argentinian writer Jorge Luis Borges, based on different testimonies: his links with Leonor de Acedevo —his mother— and María Kodama —his second wife—; his vast culture and devout dedication to literature, his and that of others; his country: the politicians and the disloyal military. Borges gradually builds his own impersonation of Borges.
