Juan flees Madrid and an incestuous relationship with his sister, Ana, working at a mine on the Andalucian coast. When his friendship with Rosario, a local shop girl, becomes romance, Ana shows up wanting to rekindle their affair. He resists at first, but she stays, asserting that Juan is the only man she can ever love. Juan distances himself from Rosario. The mine has problems: high cancer rates in the area caused by poorly stored radioactive waste. A foreign safety engineer, Petersen, tries to connect with Ana, is rebuffed, but lets her stay in his sea-front bungalow. Juan seeks her out to demand she leave, only to argue with Petersen. Death, desire, and longing play out.

Хуан спасается бегством от собственной сестры, воспылавшей к нему страстью. Трагедия в том, что и он любит Анну, но боится этой преступной связи. В один миг он лишился всего: семьи, работы, друзей. Сможет ли он отречься и от своей любви?
