Lius Luque plays a Professor who has been recently released from a mental institution after a violent outbreak. Beatriz Spelzini plays his wife, who is apprehensive of her husband's apparent full recovery.
When Beatriz picks up her husband Luis from the sanatorium, she is not quite sure if she should believe his psychiatrist’s pronouncement that he is fully cured. Her usually churlish, academic husband is suddenly friendly and cooperative, even willing to take a trip to Brazil’s beaches. When their cat Donatello disappears, Beatriz’ suspicions lead her to question her own sanity.
