Marvel Studios has released the episode synopsis for Agents of S.H.I.E.L.D.'s midseason premiere episode, "Epidemic."
With Whitehall gone, and the ancient alien city destroyed, Coulson and his team face a whole new set of threats.
The episode is written by showrunners Maurissa Tancharoen and Jed Whedon. Here's the official synopsis. The episodes airs March 3 on ABC.
After discovering an alien city with ties to his resurrection, Coulson and his team destroyed it before the forces of Hydra could claim its secrets, eliminating the villainous Whitehall (Reed Diamond) in the process. But new threats to the world have arisen, including Skye's father, Cal (Kyle McLachlan), who now seeks retribution against Coulson for stealing his revenge against Whitehall; a disturbing alliance between former S.H.I.E.L.D. agent Ward (Brett Dalton) and Agent 33; the enigmatic Raina (Ruth Negga), who struggles with her transformation into something inhuman by the alien Obelisk and seeks vengeance; and Skye (Chloe Bennet), who developed mysterious new powers from the Obelisk but whose lack of experience with her new abilities may threaten the safety of those she loves.
Meanwhile, Bobbi (Adrianne Palicki) and Mack (Henry Simmons) begin the next phase of a plan which seems to have grave repercussions for Coulson and his team, who are unaware that there's another mysterious force moving against them. And as Hunter (Nick Blood) is forced to make the biggest choice of his life, Coulson will find his mission threatened by this shocking endgame.
In the midseason premiere, "Epidemic," Coulson's team must deal with the consequences of their war with Hydra as shocking revelations threaten to tear them apart, and Hydra makes a dangerous move that may involve a traitor in S.H.I.E.L.D.'s midst.
