An account of the successful life and work of Spanish singer and actor Camilo Sesto (1946-2019), the portentous, almost miraculous, voice of Spanish pop music for decades, through his own point of view, told during his last interview and in many others, and through the words of those creators whose own work has been strongly influenced both by his art and his magnetic personality.

As a thirteen year old, Martha Caldwell witnessed the death of her parents in a terrible railway accident. Barely surviving the tragedy herself, Martha was struck dumb due to the shock. Now an adult, the still mute Martha lives with her uncle Ralph in the Spanish countryside. Martha's cousing Jenny arrives to be with the family but is quickly stabbed to death. It appears that a sex maniac is roaming the countryside; killing pretty young girls. The already traumatized Martha seems likely to be the next victim but the case turns out to be far more complicated than it would first seem.
