Former S.H.I.E.L.D. agent Daisy Johnson, now the vigilante “Quake”, is hunting gang affiliates of the anti-Inhuman terrorist group Watchdogs in Los Angeles when members of the Aryan Brotherhood are murdered by the fiery “Ghost Rider” in front of her. Agents Phil Coulson and Mack, who were forbidden from searching for Johnson by the new Director of S.H.I.E.L.D, are tipped off to her location by Agent Melinda May. They fly to Los Angeles under the guise of checking in on Inhuman asset Elena “Yo-Yo” Rodriguez, who has signed the controversial Sokovia Accords and is now under the jurisdiction of S.H.I.E.L.D. and the United Nations.
Agent Leo Fitz visits friend and S.H.I.E.L.D. ally Holden Radcliffe, a transhumanist doctor who is on probation after previous illegal experimentation. Fitz discovers that Radcliffe has secretly transferred his artificial intelligence AIDA into a human-like body, which he intends to be the first in a line of decoys for field agents in danger. Believing Radcliffe’s altruistic intentions, Fitz agrees to help him perfect AIDA, and to keep her a secret from his girlfriend Agent Jemma Simmons, who is in the paranoid Director’s inner circle, and takes daily lie-detector tests. Simmons realizes that Coulson and Mack are investigating Johnson, and orders May to stop them; May and her new strike force arrive to find Coulson and Mack surveilling Chinese gangsters, who they believe are potential targets of Quake.
The gangsters have bought a weapon off the Brotherhood which can help them fight against Inhumans. They open the box containing the weapon, and unleash a mystical being who turns the gangsters berserk. She secretly infects May as well, as the strike force takes out the gangsters. Johnson meets with Rodriguez, who stole medication from S.H.I.E.L.D. during their brief check with her which can help Johnson heal—her recent over use of her Inhuman abilities as Quake has been fracturing her bones. Johnson then tracks down the Ghost Rider and confronts him, but he defeats her, explaining that he only murders people that deserve it. She later sees his human form, Robbie Reyes, looking after his disabled brother Gabe.
