Marvel's Agents of S.H.I.E.L.D. returns for a dynamic, action-packed second season, with newly appointed Director Phil Coulson (Clark Gregg) - now the keeper of the secrets -- charged with rebuilding and restoring government and public trust in S.H.I.E.L.D. in the wake of the events of Marvel's Captain America: The Winter Soldier, where it was revealed evil Hydra agents had infiltrated the organization. Ever since the existence of super heroes and aliens became public knowledge after the Battle of New York, the world has been trying to come to grips with this new reality. Agent Phil Coulson, who had died at the hands of Loki during the battle, was resuscitated and brought back into action, assembling a small, highly select group of Agents from the worldwide law-enforcement organization known as S.H.I.E.L.D. (Strategic Homeland Intervention Enforcement and Logistics Division). S.H.I.E.L.D.'s mission: to protect those who cannot protect themselves from threats they cannot conceive.
