ABC has released the official episode synopsis for the upcoming third season premiere of "Marvel's Agents of SHIELD," "Laws of Nature."

"Marvel's Agents of S.H.I.E.L.D." returns for an action-packed third season on TUESDAY, SEPTEMBER 29 (9:00-10:00 p.m., ET) on the ABC Television Network, with Director Phil Coulson (Clark Gregg) and Agent Daisy Johnson (Chloe Bennet) leading the charge as S.H.I.E.L.D. searches the world for more powered people in the aftermath of their epic battle with Jiaying and her army of Inhumans. However, Coulson and the team soon find out that they are not the only group looking for these new Inhumans.

On the season premiere episode, "Laws of Nature," when Coulson and the team discover a new Inhuman, S.H.I.E.L.D. comes face to face with another organization searching for powered people. And still reeling from Simmons' dramatic disappearance, Fitz goes to extreme lengths to try to learn how to get her back.

"Marvel's Agents of S.H.I.E.L.D." stars Clark Gregg as Director Phil Coulson, Ming-Na Wen as Agent Melinda May, Brett Dalton as Grant Ward, Chloe Bennet as Agent Daisy Johnson, Iain De Caestecker as Agent Leo Fitz, Elizabeth Henstridge as Agent Jemma Simmons, Nick Blood as Agent Lance Hunter, Adrianne Palicki as Agent Bobbi Morse, Henry Simmons as Agent Alphonso "Mack" MacKenzie and Luke Mitchell as Lincoln Campbell.

Guest starring are Constance Zimmer as Rosalind Price, Matthew Willig as Lash, Juan Pablo Raba as Joey Gutierrez, Andrew Howard as Banks, Ido Mor as Yusef Hadad, Jude B. Lanston as soldier #1, Daniel Messier as heavy and Kate Hilliard as Tina.

"Laws of Nature" was written by Jed Whedon & Maurissa Tancharoen and directed by Vincent Misiano.

"Agents of S.H.I.E.L.D." already announced a "Secret Warriors" storyline for season three. In the "Secret Warriors" comic series by Brian Michael Bendis, Alex Maleev, Jonathan Hickman and Stefano Caselli, Daisy Johnson (a.k.a. Quake) leads a sleeper team of superpowered peers called a caterpillar team. After Terrigen was exposed to the general population at the end of "S.H.I.E.L.D.'s" second season, leading to an anticipated boom of Enhanced people, it seems as though Skye will get her own sleeper super team in the show -- something that was teased when Coulson handed her a blue folder labeled "Caterpillar" in the season finale.

"Agents of S.H.I.E.L.D." season three premieres Tuesday, September 29 at 9 pm EST on ABC.
