As Hive escapes from S.H.I.E.L.D. headquarters after an incredible fight with Daisy and infecting several agents with his Inhuman gas, the agency is taken over by the primitives and it's a fight for their lives.
Hive and his crew take over Zephyr to fly up and unleash their final plan and dominate the world, but with Daisy being held hostage and May and Fitz stowing away on the Zephyr, it's one messy fight.
Jemma outsmarts the primates in the agency and the rest of the team are able to escape and meet onboard the Zephyr, where their final mission as a whole team begins.
But after Yoyo takes bullets for Mack, she's out, and Lincoln has a bad injury from hellfire, and their numbers keep dwindling as Hive continues to be one step ahead.
In the end, Daisy was willing to sacrifice herself when she had all the ingredients from her vision: the necklace and the jacket. Lincoln wouldn't let her.
Instead, Lincoln took matter into his own hands, stole the necklace, and used his powers to knock her off of the Quinn jet, taking off into the atmosphere with Hive, but not before he tells Daisy he loves her.
