Madame Hydra lures S.H.I.E.L.D. into a trap where she captures Pierce and brainwashes him into being her second as she raids the Pacific islands for recruits for the new Hydra.
S.H.I.E.L.D. inaugurates the launching of the new helicarrier, with a new crew of agents (trained by Gabe Jones) who set sights on the new Hydra island base.
