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.
