The Idea Factory - The Returned
A group of kids have been kidnapped over the years from parents that were later influential in the government. Two became spies, and one was the president. One of them headed up a task force dedicated to finding missing kids like theirs. When the kids were discovered, they were all together, having grown up together and bonding like siblings. Only not all of them were how the parents remembered them.
The twist is that they were trained to be spies for a foreign government. A few had died over the years and replaced with look alikes. It's one of them that ends up getting the whole group discovered, but the president's kid is really their kid. When the decision comes down on what to do with the kids, can the president be trusted to make the right decisiion?
