Fan Casting Elephant Memory

A dozen people, coming from all over the world, wake up in a strange dark room that seems to have been abandoned for a long time. Realizing that they were drugged to be brought here, they all blame each other, before seeing a message on television. The one in charge of their coming here informs them of the fact that they are all on a tropical island unknown to all. They are there because they have all committed horrible known crimes but have gone unpunished. If they want to get out of it, they'll have to collaborate, but this is very complicated for paranoid criminals who don't trust anyone. On the island, there is a huge lone elephant and bred to be a man killer by the man who brought them here. Like these "guests", with their past victims, he will show no mercy on those who don't run fast enough !
