The official poster of ABC and Marvel Entertainment's superhero series "Agents of SHIELD" Season 2 has been revealed that features prominent cast members of the show and the debutant antihero, Ghost Rider.

The plot of Season 4 follows the after events of Sokovia Accords and destruction of Hydra, after which SHIELD no longer needs to carry out its missions discreetly as the agency has been legitimised again.

In the previous season, Director of SHIELD, Phil Coulson (portrayed by Clark Gregg) had died. However, Coulson is not actually dead, but is undercover and is supporting Mack (portrayed by Henry Simmons) to track down the whereabouts of rest of the Inhumans.

Both Coulson and Mack have been trying to find Daisy aka Quake (Chloe Bennet) for a long time as she had gone rogue in order to protect others from her uncontrollable powers. Even the new Director of SHIELD blames Daisy for all the destruction she has done and is now after her.

Elsewhere, Agent May (portrayed by Ming-Na Wen) will be training the specialist strike teams, while Fitz (portrayed by Iain De Caestecker) and Simmons (portrayed by Elizabeth Henstridge) will take a new step towards their relationship.

However, after Simmons being appointed as Special Adviser to the Director in Science and Technology, it will become a tough task for the rest of the team to confide in her with the crucial information regarding Coulson or Mack.

The key element of the season will be Ghost Rider aka Robbie Reyes (portrayed by Gabriel Luna). The character will be a significant part of the plot-line this season.

Explaining the character of Ghost Rider, Chloe Bennet said: "It's a different version of a powered person than we've seen on the show. Everyone who's powered on our show, it's been rooted in something that Fitz and Simmons could prove through science and research. I'm curious to see how this take of Ghost Rider is going to be explained by our very logic thinking Fitz and Simmons."

'Agents of SHIELD' Season 4 Episode 1 titled 'The Ghost' will premiere on Sept. 20 on ABC.
