It's 2135. Scientists made an experiment. They only need 16 kids to start it. Why do they need them? To test how would they live,react and what would they do in situations like this. The thing is they send them back to different times. To the times before Christ was born and after that. These kids have to do a lot of challenges, they'll meet a lot of terrible things and they found friends, love. But the only thing which is the most important is to find something or someone that will take them to the next level. Shall we begin?
