(Minor spoiler alert.)

The Maryland State House makes its debut in the new season of “House of Cards” in the third episode around the 35-minute mark. Shortly after that, sharp-eyed viewers can also catch a glimpse of Cynthia Busch, the wife of the Maryland House speaker.

The cast and crew of the Netflix series took over the historic capitol in Annapolis for two days of filming in June. It was disclosed at the time that the House of Delegates chamber was being used as a stand-in for the U.S. Senate in the Washington thriller.

The drama that plays out there — involving fictional Vice President Frank Underwood, the scheming Kevin Spacey character — became available for public viewing on Feb. 14, when Netflix released all 13 episodes of season two. We won’t give too much away, other than to say that Underwood presides over the Senate in a characteristically strong-armed fashion. And that handcuffs are involved.

Cynthia Busch, wife of Maryland House Speaker Michael E. Busch (D-Anne Arundel), has a small on-camera role as one of the U.S. senators in the scene.

The main staircase between the first and second floors of the State House is also part of the action. In real life, it leads from the floor where the legislature meets to the floor where the governor and his staff work.

Prior to shooting in June, the Maryland House chamber was redecorated a bit. Portraits of past speakers were temporarily removed, and a couple of rows of desks were taken out. The crew of “House of Cards” also installed fake marble around the dais and more ornate doors in the chamber.
