An Island Of Their Own (2001)

Four good friends remain in touch after graduating from high school. Life has taken them down very different paths, yet every year they find time to leave city life behind and travel to the countryside to reminisce about their shared memories. As they do every year, they set their sights on their uninhabited island. They pay no heed to the initial ominous signs. After setting up camp, a Serbian barge moors next to the island, carrying Predrag, an experienced sailor. When one of the boys accuses him of stealing his fishing rod, tempers flare: one night, they kidnap the man and begin to interrogate him. The conflicts between the good friends become increasingly apparent, and old grievances that had been suppressed come to the surface...
