Following the defeat of Deckard Shaw and Mose Jakande, Dominic “Dom” Toretto and Letty Ortiz are on their honeymoon in Havana when Dom’s cousin Fernando gets in trouble owing money to local racer Raldo. Sensing Raldo is a loan shark, Dom challenges Raldo to a race, pitting Fernando’s 1949 Chevrolet Fleetline against Raldo’s 1956 Ford Fairlane Crown Victoria, and wagering his own 1961 Chevrolet Impala. After narrowly winning the race, Dom allows Raldo to keep his car, saying his respect is enough and leaves his cousin with his own car.
The next day, an elusive woman named Cipher coerces Dom into working for her by showing him something on her phone. Shortly afterward, Diplomatic Security Service (DSS) agent Luke Hobbs recruits Dom and his team, comprising Letty, Roman Pearce, Tej Parker, and Ramsey, to help him retrieve an EMP device from a military outpost in Berlin. During the getaway, Dom goes rogue, forcing Hobbs off the road and stealing the device for Cipher, who is a cyberterrorist.
Hobbs gets arrested and locked up in the same high-security prison which holds Deckard Shaw. After Hobbs and Shaw both escape the prison, intelligence operative Mr. Nobody and his protégé Eric Reisner recruit them to help the team find Dom and capture Cipher. Deckard reveals that Cipher had hired his brother Owen Shaw to steal the Nightshade device and Mose Jakande to steal God’s Eye, Ramsey’s software program, which has made Cipher target Dom due to having interfered with her plans. The team tracks Dom and Cipher to their place, moments before the latter two attack the base, injuring the team and stealing God’s Eye.
Roman suggests that Brian O’Conner would know what to do, but Letty reminds him that they promised not to bring him and Dom’s sister Mia in any more dangerous activities for the sake of their children. When Dom shows signs of frustration with Cipher, she takes him to see his ex-lover and DSS agent Elena Neves, and their son, of whose existence Dom was unaware, having kidnapped both to secure his loyalty and turn on his team; if Dom defies Cipher, she will execute Dom’s son. Elena tells Dom that she wanted him to decide the child’s first name, having already given him the middle name Marcos.
