An alien, with the ability to travel through time, visits our planet at various eras.

Since the car accident that caused the death of his wife, the comics author Stéphane Destouches sinks into alcohol and wanders the roads of Morocco.

The legend of Tristan and Isolde is one of the most beautiful love epics ever conceived. Richard Wagner, in a famous opera, had already tarnished its purity. The modern transposition of the legend is set in Brazil, in a village of poor fishermen on Guanabara Bay, framed by mountains not far from Rio de Janeiro. Two young cousins, Marcos and Jeronimo, get together to fish successfully - the arrastao is a large fishing net - and to resist the ugly local landowner, who sets the rules and the prices. This owner has a niece: Emaïsa, who loves Marcos and is loved by him.
