Watch 'Madam Secretary' Season 2 Episode 15 online: Is there hope for Henry? [Spoilers]

Fans of "Madam Secretary" have been put through an emotional turmoil of sorts. The CBS political drama has focused on real world issues such as the lure of extremist ideologies, nuclear attacks, and the personal tragedy that occurs from a terrorist attack on another country's soil. The latest instalment, Season 2 Episode 15 titled "Right of the Boom," will be also underlined by these themes.

Last week's episode titled "Left of the Boom" concluded with a heinous terrorist attack in the U.S. The blast, carried out by Hizb al-Shahid, targeted Saudi Arabian women's right activist Noura Al-Kitabi at a lecture hall. Although Elizabeth McCord (Téa Leoni) was safe, her husband Henry's condition was precarious. His effort to save the people at the lecture hall exposed him to uranium radiation and fans wonder if he will survive.

The promo for the upcoming episode indicates Henry (Tim Daly) will continue to fight for his life at the hospital. The doctors will inform Elizabeth that their medical assistance may not help Henry. Even if Henry does survive, we predict that he may not be the same anymore.

While Elizabeth worries about her husband, President Dalton (Keith Carradine) will ask her to focus on the intelligence gathered after the attack. The promo pictures revealed on CBS's website prove that the intelligence agencies will make headway by finding a crucial clue. However, how will the President use this information?

Is U.S. on the verge of a war?

Season 2 Episode 15's synopsis released via TV Guide reads:

"A shocking event occurs on U.S. soil, which sends Elizabeth scrambling for answers as President Dalton questions how this was able to happen in the first place."

"Madam Secretary" Season 2 Episode 15 airs Sunday, Feb. 21 at 8 p.m. on CBS. You can live stream the episode via CBS All Access.
