Interrabang is a 1969 Italian giallo film directed by Giuliano Biagetti, starring Haydee Politoff and Beba Lončar.

One summer day, famous fashion photographer Fabrizio sails to a small Mediterranean island for a photoshoot, accompanied by his business partner wife Anna, Israeli model Maregalit, and Anna's sister Valeria.

A radio news bulletin reports that an escaped convict has murdered a policeman and is still on the run.

The group discover that their boat has run out of fuel, and Fabrizio hitches a ride on a passing speedboat to return to the mainland in order to get a petrol can.

So, the three women are left to explore the island, where they meet a mysterious man, Marco, who claims to be a writer.
