Hippiniada, or the Continent of Love (1997)

Synopsis

The protagonist goes on a sea cruise, during which he meets charming girls with whom he later falls in love. He is surrounded by amusing characters: a chronic bachelor, a "smuggler" barmaid, and little twin pranksters. Because of the twins' pranks, the movie characters ended up on an island that, as it turns out, belongs to an old hippie saxophonist named Hill. They believed that it was a desert island and started their new life as "robinsons". Years pass... Many children appear on the island, and Hill dies. Suddenly, everyone finds out that they are not living on an island, but at a radioactive waste dump.
