President Dalton sends the "Murphy Station" to eliminate the most-wanted terrorist in the upcoming episode 21, titled "Connection Lost," of the second season of the political drama "Madam Secretary."

US President Dalton learns that Jibral Disah, the world's most-wanted terrorist, is lying low in Islamabad. He decides to send the Murphy Station, which includes Henry, Jane, and Jose. They get on a dangerous mission to get rid of the international threat. Elizabeth and Henry, on the other hand, try to work out their relationship so they enlist in a couples therapy.

The promo trailer for "Connection Lost" reveals Henry confirming if Pakistan gave the US access to track its nuclear weapons. President Dalton tells Elizabeth that agreement is the key to global nuclear security. Elizabeth talks about securing a hundred nuclear warheads of a falling regime, as a Pakistan leader betrays his own country.

In other related news, Tim Daly explains why his character Henry, who is a religion teacher, is more involved in the intelligence community. "Unfortunately, being a scholar of religion is also being a scholar of war, because religious conflict and war go hand-in-hand," Daly told TV Line. "So I thought it was great that Henry might have some insight into what was going on globally."

Daly also did not expect to be the newest addition in the intelligence circle. He added, "After the debacle Henry goes through with his Russian operative, I didn't know what would happen. It kind of came at me out of the blue."

Meanwhile, the previous episode, titled "Ghost Detainee," saw Elizabeth deliver her first-ever speech to the United Nations General Assembly. She talked about condemning the terrorist group Hizb-al Shahid and creating an alliance together with the Russian Foreign Minister.

"Madam Secretary" season 2 airs every Sunday at 8 p.m. on CBS.
