The script is a free adaptation of the short story “Letters to a lady in Paris” by Julio Cortázar. Andrés is a veterinarian who suffers from a strange anomaly: from time to time, he vomits little white bunnies. Naturally, one is not going to comment on it, so he does his best to hide it. It wasn't so terrible, once he got into the unvarying cycle, the method. The problem is that there are now ten of them.
