CIA Season 1 Synopsis, Courtesy of CBS:
When by-the-book FBI Special Agent Bill Goodman (Gehlfuss) is loaned out to a clandestine CIA/FBI task force, he finds himself teamed up with secretive and roguish CIA Agent Colin Glass (Ellis). Together they will work covert operations in New York, uncovering international plots, terrorist cells, and geopolitical secrets.
Bill will learn the rules of this murky world on the fly as Colin leads him deeper into spy games where only one thing is clear—their work keeps America safe, even if no one will ever know what they did in the shadows.
