Agent Peggy Carter is back - and she's not taking any prisoners.

The "Captain America" ass-kicker doles out some pain in this new clip from "Marvel One Shot: Agent Carter," the fourth entry in the "Marvel One Shot" series that's set to be included as a special feature on the forthcoming DVD/Blu-ray for "Iron Man 3." Also starring Bradley Whitford and Dominic Cooper (reprising his "Captain America" character Howard Stark), the short film follows Carter as she joins the S.H.I.E.L.D. organization and attempts to track down the "Zodiac" key - all while battling her sexist boss (Bradley Whitford), who feels women have no place in the organization.

Check out the clip below and let us know what you think.

"Iron Man 3" will be available on HD Digital and HD Digital 3D September 3, and on 3D Blu-ray, Blu-ray, DVD, Digital Copy and On Demand September 24.
