“Marvel’s Agents of S.H.I.E.L.D.” returns for a dynamic, action-packed second season, with newly appointed Director Phil Coulson – 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. This won’t be an easy job to accomplish with the majority of S.H.I.E.L.D. agents either killed, secretly working for Hydra or free agents.
