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.

With the Zephyr's time drive malfunctioning, the team is quite literally hurling toward disaster and Yo-Yo may be their only hope. The only problem? To get her powers back, she'll need to enlist the help of an old adversary and revisit part of her past long hidden away.
