Aduthathu shows 10 people being taken to an uninhabited island for a TV reality show. The survivor gets to walk away with a huge cash award. The 10 are on the island and events unfold. It is hard not to notice similarities to many Hollywood thrillers that we have seen before, but this one does not look like a rip-off from any of them; it retains its originality. Coming back to the plot; the 10 realize that all is not well on the island and that the survivor game is becoming serious business. Disappearance of the contestants one by one adds to the consternation, and no one is clear as to how or why this is happening. And, that is when they realize the most important fact of the entire episode are they in a reality show?
