We begin with Ellison answering his front door. Knock-knock, it's . . . another Ellison. But just as fake-Ellison is about to shoot real Ellison, a metal pipe is thrust through fake-Ellison's chest from behind, and a hand comes through the hole to pull out the terminator's "heart." It's Cromartie, who tells the confused Ellison "Skynet does not believe in you like I do; you will lead me to the Connors."
Sarah, John and Cameron return home to find out they've been robbed. The guilty party made off with diamonds, cash, credit cards and IDs, as well as food, which means the criminals were human. Sarah calls Derek (who is in bed with Jesse) to tell him she's worried about the security risk of the IDs making it into the system and they plan to meet downtown. John admits to Sarah that the mistake was his, that Riley forgot to reset the alarm when she left.
We cut to the halfway house Cameron had visited several episodes earlier and see that her picture is just now being entered into the county's database. As it goes into a scanner, Cameron's picture immediately pops up on a computer screen in Cromartie's car.
Cromartie arrives at the halfway house, pretending to be Cameron's uncle. The woman behind the desk isn't buying it, but he happens to run into Jody (Cameron's buddy that episode) while he's there. Jody, who has a vendetta against Cameron, gives up the fact that Cameron had a "brother" named John and agrees to help Cromartie.
Police arrive at Ellison's residence and arrest him for the murder of Peter Meyers.
Sarah, Derek and Cameron visit a diamond fence named Moishe (friend of Jesse's) who happens to have a good deal of their jewels in his possession. He tells them he got the stolen merchandise from a Walter Ostrowski.
Jody takes Cromartie to a grocery store, coincidentally at the same time John and Riley are there shopping. Some dumb luck (Jody accidentally knocking stuff over) prevents Cromartie from finding John.
We cut to a police station, where Ellison has been picked out of a lineup. During questioning, Detective Kaplan accuses Ellison of killing Meyers and that unless he has an "identical twin" he doesn't have much of an alibi.
Sarah & Co. find Ostrowski, who happens to be a dentist. It turns out that Ostrowski did not rob them, but instead is in debt to Moishe. Sarah and Derek argue following this development, with Derek questioning both security and John's overall maturity.
A very angry Sarah returns to Moishe's office. After Cameron effortlessly tosses his gigantic bodyguard into some shelving, Moishe gives up that he actually got their diamonds from a guy named Tristan Dewitt
The show briefly gets much, much better as Derek visits a tiny bikini-wearing Jesse. He warns her about how freely Moishe is using her name and she tells him she's not missing anymore sunsets, whatever that means.
Cromartie, having gotten rid of the increasingly annoying Jody, arrives at Kacy's door waving Cameron's picture. She lies to him and he walks off, but not before asking about the on-the-market house next door. Kacy calls over there to warn John and Riley, who have just returned with the groceries.
Cromartie knocks on the door, and over John's protestations Riley opens it to "get rid of him." After asking about Cameron, Cromartie walks past Riley and examines much of first floor. John, who has grabbed an enormous shotgun from under the sink, manages to hide from Cromartie before he eventually leaves.
Sarah and Cameron visit with Dewitt's parents, who tell them their son is a habitual thief who lives with them and works at a local video store.
Weaver visits the orange jump suit-wearing Ellison in the hooscow. He tells her something has happened, but that he will not discuss it while in custody.
After Cameron explains the Biblical story of the Brothers of Nablus (our episode title) to Sarah, Sarah gets a call that her credit card has been used at a local bowling alley. We cut to Cromartie, who sees the exact same information flash across the screen in his convertible. Oh crap.
The detective who interviewed Ellison earlier re-interviews the witness who saw fake-Ellison commit the murder. With (a little too much) help from the detective, the witness describes hearing a noise and seeing Ellison materialize, completely nude, from an energy bubble by the side of the road and snap Meyers neck with his bare hands.
We cut to the bowling alley, where the unshaven Dewitt is describing a terrible movie idea to two of his friends, and holds up the diamonds just as Sarah and Cameron walk in. The fellas quickly hand over the remaining stolen goods and credit card. Spotting another pair of shoes, Sarah begins walking away to look for the fourth person. As she does Cameron shoots all three men, coldly saying "they knew where we lived." Sarah seems bothered by this. When she finds their friend (Nicholas) in one of the bathroom stalls, Sarah tells him at gunpoint never to tell anyone about the robbery or that he has seen Sarah. When Sarah leaves the bathroom she lies to Cameron, telling her "all clear."
Back at the police station, the detective tells Ellison he's free to go, that particulars of the witnesses' statement were so fantastic they destroyed his credibility. As the detective leaves the station we see him turn into Weaver.
Derek shows up at Moishe's to find the fence with a bullet hole in the middle of his forehead. Turning the corner he finds himself gun barrel-to-gun barrel with Jesse, who has done the deed.
An upset Ellison shows up at his old house, and has a non-specific conversation with his ex-wife about how confused he feels about his current line of work. Sarah and John argue back at the house about Riley and security, with an emotional John asking why Sarah didn't protect him when he had to kill Sarkissian.
Ellison shows up at Weaver's office, telling her that there had been an identical copy of him running around and that he is under the impression he is being tested. Almost with a smile, Weaver asks Ellison who he thinks saved him.
Back at the bowling alley we see that Cromartie has the fourth friend of Dewitt's tied up. As the show comes to a close it appears that the kid is about to break and give up the goods on Sarah.
