Gadgets in colorful backpacks and experiments to develop a time machine; this film appears to be a retro youth film.
There is, however, nothing childish about the time travel adventure the main characters (CJ and Sebastian) are experiencing. CJ's brother is mistaken for a fugitive and is shot by the police. CJ and Sebastian go back in time to save him. But they couldn't expect the consequences; if CJ's brother is not the victim, then another innocent African-American boy is. Who has to be the victim?
