Plot summary
In 1973, the agents return to the speakeasy to discover that S.H.I.E.L.D. is preparing Project Insight, which should not be developed for several more decades, led by Wilfred Malick, who should have died in 1970. Wilfred and the Chronicoms attempt to capture the agents, but Daisy briefly takes his son Nathaniel (who also should be dead) hostage to allow their escape. Nathaniel sees Daisy use her powers. The agents reunite with Enoch and return to the Zephyr. Without warning, the Chronicoms jump forward to 1976 when Project Insight is set to launch, and the Zephyr follows.
Coulson and May plant explosives in the Lighthouse where Insight is being launched while Deke and Yo-Yo confront Wilfred, who is killed by Deke. Daisy and Sousa are captured by Nathaniel. Mack aborts the detonation when he sees his parents, John and Lilla, are being held captive, allowing Insight to launch. The agents use the Zephyr to destroy Insight, giving away their location. Nathaniel attempts to call Daniel Whitehall to transfer Daisy's powers to himself.
