In The Name of Family

Billy goes back in time to try to stop his older brother from turning evil. If he succeeds, he'll not only save his brother - he'll save the world. If he fails, the future is doomed to the fate Billy grew up in. It's a terrible future, one he'll do almost anything to avoid. Almost, because he's not willing to lose his brother in the process of trying to save the world. The only thing standing in his way is his family. They don't trust him and want him gone. He can't tell them who he really is so he's got an incredibly difficult task ahead of him.
