Warning: Spoilers Below for F9

F9 includes appearances by young versions of several major characters in the Fast & Furious family. The latest installment of the perpetually over-the-top action series takes the family dynamic to new levels, bringing Vin Diesel's Dominic Toretto into conflict with his estranged brother Jakob, played by John Cena. Dom's sister Mia also makes a return to the series, with Jordana Brewster reprising the role.

With Jakob in the employ of the franchise's new arch-villain Cipher, played by Charlize Theron, F9 takes the new angle of bringing a fracturing of Dom's birth family, with his and Jakob's falling out occuring due to Dom's belief that Jakob was responsible for their father's race track death. Jakob, in turn, has his own information that he's withheld from Dom for the last few decades.
