It’s the mission “Marvel’s Agents of S.H.I.E.L.D.” fans have been waiting for: the Secret Warriors are coming together. In the last episode, Giyera (Mark Dacascos) escaped his cell and tried to take down the plane with nearly every agent on it, except Daisy (Chloe Bennet) and Lincoln (Luke Mitchell). The two will need a little backup to save their friends in Season 3, episode 17 of the ABC drama.

“Agent Daisy Johnson must call upon the Secret Warriors for an inaugural mission that will leave no member unscathed,” the synopsis teases. Joey (Juan Pablo Raba) and Elena (Natalia Cordova-Buckley) will have to be ready to face Hydra in this episode, titled “The Team.”

In the trailer, Coulson is shown in his office, so it looks like the Secret Warriors mission is successful. However, the video also warns that they aren’t all good guys. “One of these combatants is not what they seem,” the voiceover warns. Will someone betray the team?

Watch the “Marvel’s Agents of S.H.I.E.L.D.” Season 3, episode 17 trailer below:

After the agents are saved, they’ll find out more about their newest villain, Hive (Brett Dalton). It seems his alien abilities could be more disturbing than they realized. “S.H.I.E.L.D. learns more about Hive’s powers, forcing them to question everyone they trust,” the summary reveals.

Hive’s powers could be a little too alluring to the Secret Warriors. Executive producer Jed Whedon implied that viewers should be concerned about the new Inhumans being brought to the dark side. “He does like Inhumans,” Whedon told Entertainment Weekly. “Both teams like Inhumans on their side, so I think that he would jump at any opportunity he has to increase his ranks. There is definitely going to be a showdown right off the bat.”

“Marvel’s Agents of S.H.I.E.L.D.” Season 3, episode 17 airs Tuesday, April 19 at 9 p.m. EDT on ABC.
