Dom is daddy Dom now, and though he says he can’t live his life a quarter-mile at a time anymore, we suspect that will change real quick if his son is threatened. The trailer opens with the peaceful setting we saw early this week in the teaser clip, but from there the world goes all furious on us without any further mention of the youth. Instead, it turns out Dom has a younger brother played by John Cena in the flic. He also doesn’t seem to like Dom very much, but being a Toretto, he has a penchant for – you guessed it – driving fast. He also has some connection to Charlize Theron’s Cipher, who was the main baddie in Fast 8. So in a nutshell, there’s your plot.
