Meanwhile, Walker secures a perch for his mission, Brody makes his final preparations for the Vice President’s policy summit at the State Department, and Saul continues to investigate the unsettling implications of Carrie’s timeline.

The pieces of a deadly puzzle are falling into place, but as she musters the energy to do what she needs to, Carrie may be too late to put it all together. When the crisis finally hits, no one can foresee the outcome of Abu Nazir’s long-awaited attack.
