The plot is the same - a colony of clones is groomed for rich bastards who can afford to pay for replacement body parts. When the clones bodies are needed, they are told they have won the lottery and will be shipped out to live a wonderful life on "the island."
One clone discovers something from outside their compound, which leads to more discoveries and the horror of the truth. The clones escape to try to tell their sponsor what is really going on, assuming that they will be horrified and stop the death of the clones. Huge gap in the reasoning since the person has paid to have this clone grown in case they need the body parts.
