Superhumans from the Past

Steve and four superhumans he never met before in his life assemble in the middle of a deserted island. The five superhumans meet in a time of turmoil during the Cold War and dawn of the South American revolution, but they're propelled to the future where they learn that the past is not set in stone. On top of it, everyone is way out of their comfort zone as they find out they're no longer on Earth, but on a planet called Arlos. Time travel is a thing many do not believe possible, but if you could go back in time, why would you? To change the past is a paradox which even superheroes seem not to escape from except that this time it's not a paradox for the five superhumans, known as the Five Ghosts.
