I call it to be some of most mysterious and curious movies ever been. Why I call this because the plot of this movie is silently awesome.
Plot: Two persons who are American federal army officers have gotten a case of a woman who is missing in a jail which is situated on a island. The officers think that theres something terribly wrong with the place and even the authorities can be indulged in this. Officers claim there should be 67 persons but therere only 66. They think that people who are missing are used for some illegal human experiments. The MIND-BLOWING PART IS when we come to know one of those officers is the 67th person himself. And he has some sort of cyclic psychological disorder. He has murdered his wife because his wife murdered his two children. So he has imagined himself like he is an ex major of Army. This is cyclic, he knows the truth and this all starts again and again.
The performance of Lionardo DIcaprio is fabulous as expected.
I must recommend you to watch this movie.
