List of Agents of S.H.I.E.L.D. episodes

"S.O.S." is the twenty-first and twenty-second episodes and two-part season finale of the second season of the American television series Agents of S.H.I.E.L.D., based on the Marvel Comics organization S.H.I.E.L.D. (Strategic Homeland Intervention, Enforcement and Logistics Division), revolving around the character of Phil Coulson and his team of S.H.I.E.L.D. agents as they fight a group of Inhumans. It is set in the Marvel Cinematic Universe (MCU), sharing continuity with the films of the franchise. The first part was written by Jeffrey Bell and directed by Vincent Misiano. Part two was written by Jed Whedon and Maurissa Tancheroen, and directed by Billy Gierhart.

Clark Gregg reprises his role as Coulson from the film series, and is joined by series regulars Ming-Na Wen, Brett Dalton, Chloe Bennet, Iain De Caestecker, Elizabeth Henstridge, Nick Blood, and Adrianne Palicki. The episodes conclude storylines from throughout the series, and set up new plotlines and mysteries for the next season, with several recurring guest stars making appearances, including Kyle MacLachlan, Henry Simmons, Dichen Lachman, Ruth Negga, and Blair Underwood. The visual effects were completed days before the airing of the episodes, while more traditional practical effects were used where possible.
