Homeland Season 4 Spoilers: New Episode Features Tense Prisoner Exchange for Carrie, Saul, Quinn

The newest episode of Season 4 of Homeland was a tense and dramatic one, as Carrie and Quinn tried to get Saul out of Taliban custody and return him home safely. They nearly succeeded, but Pakistani intelligence was onto the plan the whole time and Haqqani's men recaptured Saul, who screamed at Carrie over the phone for betraying him and not bombing them all off the map like he asked.

This Sunday's new episode will focus on the prisoner exchange to free Saul, in which Haqqani will receive five of his captured associates. But as one might expect, the operation won't go smoothly. The following comes from the "Mega Buzz" column at TV Guide.

"The episode's key setpiece involves a long, nerve-wracking prisoner exchange that goes awry almost from the start - and it's an angry Saul who starts the trouble! Amidst Saul's (understandable) tantrum and the threat that either side could open fire at any moment, Carrie will have to be at her best to once again talk her mentor off the ledge. But, naturally, it's only after you get a moment to breathe that the show hits you with the episode's real doozy."

Remember that Saul was prepared to kill himself in the last episode to avoid recapturing, but Carrie convinced him not to do it in an extremely tense scene. The "Ask Ausiello" column at TVLine also warns that the next episode will keep you gripped.

"This Sunday's episode ranks among the Top 5 best Homeland episodesever. Much of the focus is on the prisoner swap - Saul in exchange for those half-dozen terrorists - and Carrie's familiar feeling that something is amiss. I'm not going to tell you if her suspicions turn out to be correct, but I will tell you to make sure the edge of the seat is comfortable, because you'll be fused to it during much of the hour."
