Fan Casting Monster Island

Set a few years after the events of "Monster Park", a major plane carrying the American vice president was diverted from its route and crashed, no one knows how, on the island. Since no nation has the legal authority to go to this island, which has been classified by the UN, a member of the government unofficially hires a group of mercenaries to infiltrate the island, now in the hands of the monsters who were once prisoners there. They're not guaranteed to find the vice president alive, but they must try, even though they're in the only place on Earth where their very high-level military training may not be of any help !
