The upcoming Madam Secretary Season 5 Episode 17, titled "The Common Defense," will be tackling real-life events - the measles outbreak and climate change. The disease has affected a lot of people in the United States, and one of them is Daisy's (Patina Miller) daughter, Joanna, who will be in danger.

"While Elizabeth (Tea Leoni) is away on a retreat thinking about her presidential campaign, her staff tries to secure an international agreement to protect citizens who have been displaced due to global warming," Madam Secretary Season 5 Episode 17 official synopsis read. Also, the staff works to contain a measles outbreak that threatens the life of Daisy's daughter, Joanna."

The show has yet to explore Daisy's storyline for a long while, so it may finally happen on Madam Secretary Season 5 Episode 17. Unfortunately, it will be about the medical condition of her daughter, per CarterMatt. Fans know how dangerous measles can be, so things may get emotional as they try to save Joanna's life.

Elsewhere, fans will see an update about Elizabeth's plan to run for the presidency on Madam Secretary Season 5 Episode 17. Although the Secretary of State has yet to announce her bid, it may soon happen as the show is about to come to an end.

Talking about global warming on Madam Secretary Season 5 Episode 17, the show may help to give light to this worsening issue. As the series depicts real-life events, it may be the right time to touch this topic.

So to protect the people affected by climate change, Elizabeth's staff should bring them to Tangier on Madam Secretary Season 5 Episode 17. The island in Chesapeake Bay of Virginia is said to be a "major climate casualty," although it is not yet revealed if it would be seen on the show.

Meanwhile, Erich Bergen, who plays as Blake, revealed Madam Secretary Season 5's production has wrapped up. In a post on Instagram, the 33-year-old actor shared a group photo with hashtag #RenewMadamSecretary.

 
CBS has yet to renew the show for Season 6, but fans and cast alike are hoping it will finally happen. As Madam Secretary Season 5 Episode 17 is about to come out, there will be only three episodes left before this season officially comes to an end.

As Elizabeth plans to run for the presidency, Madam Secretary Season 6 may feature her political campaign, while still working as a Secretary of State. So while fans are still waiting for the renewal announcement, they should watch Madam Secretary Season 5 Episode 17 on Sunday, March 24, at 10 p.m. ET/PT on CBS.
