Below is the synopsis for the show:
BRAINDEAD is a comic-thriller set in the world of Washington, D.C. politics that follows Laurel, a young, fresh-faced Hill staffer who discovers two things: the government has stopped working, and bugs are eating the brains of Congress members and Hill staffers. The daughter of a Democratic political dynasty who left Washington, D.C. to become a documentary filmmaker, Laurel is pulled back into the family business when her brother, Luke, the Democratic whip Senator from Maryland, needs her help running his Senate office. On the Hill, Laurel becomes unlikely friends with Gareth (Aaron Tveit), the smart, hardworking Legislative Director to a top Republican, Senator Red Wheatus (Tony Shalhoub). Her other allies include Gustav (Johnny Ray Gill), an eccentric genius who is the first in D.C. to recognize that something sinister is attacking the Capitol, and Rochelle (Nikki M. James), a medical student who teams up with Laurel and Gustav to protect and defend the citizens of D.C. from an untimely fate. As the tiny bugs continue to multiply, Laurel and her allies must work quickly to identify the creatures, stop their infiltration and ultimately save the world.
