Coulson and the team set out to rewrite the course of humanity's fate; they're unaware that their efforts will dramatically change one S.H.I.E.L.D. agent's life.

Coulson and the team find themselves under siege at the Lighthouse.

After a bumpy landing in the disco decade, the team – Daniel Sousa in tow – reunites with more than one familiar face at the S.H.I.E.L.D. hangout and discovers exactly how to dismantle the Chronicoms’ latest plan. But when they get too close for comfort, the Zephyr unexpectedly leaps forward again, this time to a date pivotal to not only the future of S.H.I.E.L.D. but to the future of Director Mack as well.

The stakes are higher than ever when, after blowing their cover and damaging the Zephyr in the process, the team must scramble to rescue Mack’s parents, save S.H.I.E.L.D. from a Chronicom infestation, and fix the ship … all before the next time-jump. Meanwhile, Daisy and Sousa find themselves at a disadvantage against a power hungry Nathaniel Malick and his goons, and Coulson will have to do the thing he does best in order to save the future.
