I saw this film when I was a kid and I remembered loving it.
I really don’t know the name but I do remember it definitely was an asian film. And filmed before 2005 I believe.
It was about a women or 2 women (not so sure) were sent to a prison on an island where they had to train everyday, and everyday they fight each other and tries to kill each other to survive, and the last one that survives gets to leave the island.
And I remember the ending where, 2 best friends I believe, had to fight each other, but in the end, the “women” who ruled the prison invited them to each with her, and poisoned the foods, and I believe all three of them died.
I am not quite sure about the events either, but this is all I know.
Does anyone know the name of the movie?
