The Sex of Angels

Nora hatches a plan with her friends Nancy and Carla to take Nora's father's yacht without permission and sail toward the Dalmatian coast. They decide to recruit a desirable male to join them on the voyage. The mood is reckless, setting the tone for the journey.

The trio meets medical student Marco at a dance club. Although he has a casual girlfriend, he agrees to join the trip and meet Nancy the next day for a swim.

The women abduct Marco onto the yacht, catching him by surprise as the plan shifts from flirtation to selection. He is initially amused and tries to charm each of the women as they move toward their larger scheme.

When the yacht reaches Croatian waters and faces a routine inspection, the women reveal their true intent: to experiment with LSD and to tape their trip because they might not remember details.

The foursome ingest sugar cubes dosed with LSD and submit to the drug, beginning their altered voyage. The trip starts to blur memory and perception, affecting how events unfold.

The next morning, Nora is in pain; Marco discovers Nancy and Carla in bed and realizes a bullet remains embedded in his chest, leaving him at high risk of death. The women remember nothing of the night and are reluctant to revisit the taped memories.

The yacht pulls into a Croatian port to obtain morphine for Marco. The druggist initially refuses without a prescription, but Carla offers herself as a virgin in exchange for the drug.

Back on board as Marco weakens, Carla urges returning quickly to Italy for hospital care, but Nancy and Nora fear blame and arrest and slow the journey home.

Before reaching port, Marco succumbs to his wounds. They try to hear what happened during the LSD trip by playing the recording, but the tape is blank because Nancy did not switch on the microphone.

Marco's body is set adrift in an inflatable dinghy as the yacht finally docks and they return home with a facade of composure masking their guilt.

Back home, the fragile bond among the women shatters as Carla leaves Nora and Nancy, runs to the end of a pier, and drowns herself after contemplation.
