Sometimes the "Best Laid Plans" of Kree and Men go awry. Kasius has planned to capture the Destroyer of Worlds, kill the Agents of SHIELD, and destroy what remains of the Earth and its people. But our heroes aren't going to make it that easy. The team on the surface continue to discover clues about their ultimate fate in the past, while preparing the Zephyr for an escape flight. They better hurry too. The gravity storm that is almost upon them will last for weeks. Back at the lighthouse, Mack and Yoyo lead the citizen in a defense against all that Kasius can throw at them. But the wily Kree has wired the entire structure to blow up whenever he sees fit to end it all and escape with his prizes, Daisy and all the Inhuman children. It's a standoff for the fate of everyone. The Zephyr does take flight, but it has an unexpected, dangerous passenger when Sinara sneaks on board and battles it out with Daisy. The race to save Flint continues. Jay and Josh appreciate the usefulness of plastics on this week's Agents of S.H.I.E.L.D.: Case Files.
