We've officially reached the halfway mark of Homeland's stellar second season and all the plotlines are coming to a roaring boil.

Last week dealt the C.I.A. a tough blow as a terrorist raid on the tailor's shop left almost every agent dead and the enemy absconding with a secret box worth killing for. Sunday's all-new episode, titled The Clearing, not only reveals what was in the box, but how essential it now is for Carrie & Co. to stop Abu Nazir's men.

As you can see in the first of two new sneak peek clips, Brody has pledged his (temporary?) allegiance to The C.I.A. so deeply, he's wearing a wire during meetings with Roya. Elsewhere, Dana is still dealing with the Finn fallout from their hit-and-run. But while the VP's son agrees to fess up to their crime in the clip below, I fear he's got an ulterior plan for dealing with Dana.

Homeland airs Sundays at 10 p.m. on Showtime.
