A young artist starts a friendship with his neighbour, a criminal who, tormented because of one of his crimes, seeks forgiveness.

Nieves has murdered the man who was tried to rape his younger brother. Sentenced to five years in prison, she is immersed in a hard and marginal world, she does yearns to one day being released and fulfill her lifelong dream: to know the flowery desert in northern Chile. When an oversight of her captors allows her to flee, her dreams will have to wait still. She dedicates herself to managing a nightclub where her former jailmates prostitute themselves.

When the Chilean officials lift the ban on harvesting the shellfish "el loco" (which purportedly is an aphrodisiac) in the seaside village of Puerto Gala greed and lust take hold. Greed is embodied by Carlos Maldonato, "El Canuto," who attempts to buy all of the shellfish for a Japanese company, and by a traveling band of prostitutes that accompany the influx of fishermen. El Canuto also wrangles to get into good stead with an old flame, Sonia, who is now the proprietor of "La Pincoya," a local restaurant. But "el loco" proves more effective, and more damaging, than anyone could have guessed.

Julito is a shy and insecure young man who works at the Night Club “El Tiburon”, where he aspires for the impossible love of Rossi, the main showgirl and also the owner's girlfriend.
