ABC and Marvel have revealed a second teaser trailer for the return of Agents of S.H.I.E.L.D., and the ramifications of H.Y.D.R.A.'s take over have never been more felt. Watch as Agent Coulson (Clark Gregg) and his team are forced into hiding, where they will live as ghosts in the shadows. Can this team of covert agents restore order and bring their organization back to prominence? Find out when Marvel's Agents of S.H.I.E.L.D. Season 2 premieres this September.

Clark Gregg reprises his role of Agent Phil Coulson from Marvel's feature films, as he assembles a small, highly select group of Agents from the worldwide law-enforcement organization known as S.H.I.E.L.D. Together they investigate the new, the strange, and the unknown across the globe, protecting the ordinary from the extraordinary. Coulson's team consists of Agent Grant Ward (Brett Dalton), highly trained in combat and espionage; Agent Melinda May (Ming-Na Wen), expert pilot and martial artist; Agent Leo Fitz (Iain De Caestecker), brilliant engineer; and Agent Jemma Simmons (Elizabeth Henstridge), genius bio-chemist. Joining them on their journey into mystery is new recruit and computer hacker, Skye (Chloe Bennet).

Marvel's Agents of S.H.I.E.L.D. Season 2 returns September 23, only on ABC.
