Is it hot in here, or is Madam Secretary‘s Elizabeth McCord on the verge of causing an international incident?

The answer is yes — to both — in this exclusive sneak peek at Sunday’s episode (CBS, 8/7c).

In the clip, Elizabeth and India’s foreign minister Chondita Samant (played by Sakina Jaffrey, House of Cards) get into a disagreement during the secretary’s first State Department trip abroad.

How does it go? Let’s put it this way: Even the unflappable Blake breaks a sweat, and not just from the oppressive heat in the room.
