Peter learns that Rabbi Lev was involved in a plot to blow up the Temple Mount in 1991, but Shin Bet never pressed charges. What if Lev has renewed his efforts to rebuild the Temple? Not only would the Arab world erupt, but also it could set off a chain of events akin to a third World War. Golan is starting to agree with Peter that this whole thing is bigger than the murder of one girl.
When the ship carrying Avram and Red docks in Croatia, they are met by a warm man named Emil and his beautiful daughter, Elena, who immediately makes Avram both uncomfortable and excited. The Essene, Shem, looks on as they drive off with Red hidden in a crate in the back of Emil’s truck.
Meanwhile, Ambassador Ridell has summoned Lynn to her office to tell her she needs to get Peter under control. She also cautions Lynn that if she’s intimately involved with Peter, she’s compromising herself.
To get intel on Rabbi Lev, Peter and Golan pay a visit to Rabbi Shimon, Golan’s uncle. Shimon says that even if the JHC gets all the stones and the breastplate, they’d need an unblemished red heifer and a high priest born from the lineage of the First High Priest, raised in isolation from birth without his feet ever touching the ground to fulfill the prophecy. He explains that the stones were scattered to the four corners of the earth, hidden for safekeeping. However, there may be a clue to the whereabouts of one of them in the War Tablet, written by the Essenes, an ancient religious sect that once lived by the Dead Sea.
In New Mexico, Charlie has been going from town to town trying to find Debbie. The waitress at the local diner tells him that she suspects Debbie is at Billingham’s compound. Her suspicions are proved to be correct when we see Debbie chained to a pole in a locked room at the compound. Even Sandra, the woman who delivers her food, won’t help her.
Emil gives Avram “regular” clothes to change into before they get to his house so Avram doesn’t draw attention to himself. Avram’s makeover draws the attention of Elena, but Avram’s hesitation with his words proves he’s more comfortable with bovine company. When they arrive at Emil’s house, Shem the Essene is laying in wait on the edge of the property.
Yussef Khalid arrives at the Israel Museum dressed as a maintenance worker and enters an air vent. At the same time, the head of the museum leads Peter and Golan to the secure room that houses the War Tablet. When they open the door, the tablet is gone and the curator has been seriously wounded. They frantically search the museum, but Yussef, now dressed in street clothes, has walked out the front door undetected.
Charlie arrives at the compound, gun in hand, and Billingham attempts to diffuse the situation by explaining that Debbie left when she started using again. After a fruitless search, Charlie reluctantly takes the box of Debbie’s personal belongings they hand him. When he’s back in his car, a ring that he seems to recognize falls out of her stuff.
During a lively dinner at Emil’s house, Avram is pulled into a circle dance and exchanges shy glances with Elena before he remembers the tenets of his faith and runs off. Not too far away, the Essene peels off his clothes and throws them into a fire by the sea. He covers himself in mud and recites the Prayer of David. Later, as Avram sleeps beside Red in the barn, the Essene enters in clean white robes. He goes to Red and whispers that the full moon will bring them both to their destiny.
Peter and Golan arrive at Megiddo a few steps behind Yussef, who has driven there on a motorcycle. Yussef cracks the mosaic, swipes the stone, and takes off. Peter and Golan chase after Yussef, but they’re too late.
At the compound, Debbie stands before Billingham and her peers. He’s giving her the chance to repent for her sins and be forgiven. She acknowledges that they saved her life but then accuses them of using her and making her an accessory to murder. Billingham asks Joshua to divine the Lord’s will, and Joshua puts the two stones Billingham has given him, one white and one black, into a leather bag. Joshua pulls out the black stone: guilty.
