An Island Of Their Own (2001)

Four close friends stay connected after graduating high school, though life has led them in different directions.

After setting up camp, a Serbian sailor named Predrag arrives on the island in a barge. A dispute over a fishing rod sparks tension, escalating to a night of kidnapping and interrogation. The friends' underlying conflicts and long-held resentments begin to surface.
