In this riveting tale we meet two couples caught in a web of conflicting passions, Diving instructor Sven Fiedler and his girlfriend, Antje, who live and work on the Spanish island of Lanzarote. When a tourist couple Jola, a soap opera actress, and Theo, a stalled novelist arrive for an intensive two-week diving experience, Sven is captivated by Jola s beauty and evident wealth.
Theo suspects that Sven and Jola have begun an affair, but oddly, he seems to encourage them. Antje looks on, increasingly wary of these new clients. Cycling through different points of view, we are constantly kept guessing about who knows what and who is telling the truth. A brutal game of temptation and manipulation unfolds, pointing toward a violent end but a quiet one, underwater, beneath the waves."
