The film explores some of Eloy de la Iglesia’s recurrent themes such as voyeurism, socialism, society's class system, and homoerotic imagery.

Elisa, a beautiful woman in her late thirties, changing her plans at the last minute, cancels her flight to London where she was going to meet her older lover.

Óscar, her wealthy aging lover, has been supporting her financially (apartment, car, money, plane tickets) in exchange for one weekend a month of her time.

She exits her apartment to investigate and finds her next-door neighbor, Miguel, dropping the freshly-killed body of his wife, Nuria, down an elevator shaft.

Knowing that Elisa has a vacation home and a boat by San Juan’s lake, near Madrid, Miguel decides to go there to dispose of the corpse sinking it in the water.

With not enough room in the ambulance to take the wounded, the police ask Miguel and Elisa to help transporting a seriously injured couple to a nearby hospital.

He tells her that his dreams of becoming a successful writer never came to fruition and that instead he settled for marriage to a wealthy woman he didn't love.

Miguel sinks the body in the lake as planned, but Elisa manages to turn the tables on her abductor who falls into the water.

Initially Elisa does not know what had happened, but Nuria explains that she was not the woman whose body was thrown in the lake, that was actually Miguel's lover.
