Previously, in episode 3, we peeked into the top secret interrogation facility at Ramey Air Force Base, and learned about two of its occupants: a 460 year old ceiba tree and Captain Cristian Monserrate Sepulveda.

In episode 4, we're introduced to Jesus Santiago, an old jibaro who's dropped off at the Spanish colonial prison named la Princesa. Right away, he meets the warden, who suspects the old man of having some connection to the wooden crate recovered by the FBI, now in the hands of John Spillers. Santiago, it turns out, has history with Spillers.
