Marvel's Agents Of S.H.I.E.L.D. Winter Finale Sneak Peek

ABC has released the first clip from Marvel's Agents of S.H.I.E.L.D. Season 3 mid-season finale: "Maveth."

After Hydra kidnapped Fitz and Simmons, Grant Ward took Fitz through the portal to Maveth, prompting Coulson to jump through and follow them in -- so acting S.H.I.E.L.D. Director Alphonso "Mack" Mackenzie has a lot on his plate already. Bobbi and Hunter give him the lowdown, and together with the rest of the crew, they assess the situation. As Hunter puts it, "This is the part where the plan turns to rubbish."

Check out the sneak peek in the video below.
