In the opening of episode 4 of Scarpetta, a flashback takes us to New Jersey in 1978, where a young Pete Marino is brutally beaten by a group of boys. His father urges him to turn the other cheek, but his mother encourages him to fight back. Marino ultimately gives twice what he received in the beating.
Present day, Dorothy invites Marino to a Michelin-starred restaurant for lunch, where Scarpetta asks Lucy for help in finding a connection between Gwen and Matt. While they're discussing this, AI Janet reveals that another woman named Cammie Rammada died at Dangerfield Island, with news reports stating that she drowned. Scarpetta and Marino call Officer Fruge, who reveals that Cammie had a head wound as well. They speak to Wyatt, a security guard at Scarpetta's lab, who says that the case went to the old ME, Debbie. Mr. Reddy offered to assist Debbie and brought several FBI officers with him.
In the past, one of Marino's contacts discovers a jumpsuit in a dumpster, and Scarpetta finds traces of the glitter goo found on the victims' bodies. Her colleague Wingo suddenly finds a piece of evidence in their fridge from Lori's case. This is a significant setback since all the evidence from that case has already been forwarded, and this lapse could cost Scarpetta her job.
Present day, Scarpetta speaks to Dr. Kaminsky, who ruled Cammie's death as undetermined. She gets awkward and asks her to speak to Dr. Reddy about it. Meanwhile, Dorothy takes Marino out for a fancy lunch and asks him to keep his phone on silent.
In the past, Dr. Reddy learns about the mishandled evidence, and Marino pretends he asked Scarpetta to test something for him. Benton joins their investigation as well. They only find her fingerprints on the evidence, and what's more, the UV light reveals that her fingers now have the shiny goo from the murder case. When Boltz arrives to keep a close eye on her, it's all a bit too much for Scarpetta. She takes her bat and goes to the incinerator, taking her frustration out on some burnt remains that are waiting to be boxed.
Present day, Scarpetta confronts Dr. Kaminsky and convinces her to do the right thing. She tells her that there was an argument over the jurisdiction of Cammie's case when she arrived on the scene. Dr. Reddy arrived soon after and made sure the case went to their department. When Kaminsky was doing the autopsy, Reddy entered the room and made sure that she marked the case as an accident. Additionally, Kaminsky saw Maggie in the car with Dr. Reddy at the crime scene.
As Marino sat down for lunch with Dorothy, a call from Lucy interrupted their conversation. Lucy asked him to check out a picture she had sent, which proved that Matt and Gwen had met at a bar. Realizing her mistake, Lucy watched in horror as Marino's anger boiled over and he stormed out of the restaurant to confront Matt.
Meanwhile, Officer Fruge and her colleague were attempting to use their warrant to search Thor Labs, but the institution refused them entry and even called in the Department of Defence for support.
Elsewhere, Benton revealed to Jinx that he knew they had been selling information to the Russians. He showed Jinx text exchanges between Gwen and another man, which caused Jinx to finally confess that Gwen would add digital trails in Thor Labs' system and he would clean it up.
In the past, Benton found Scarpetta using her bat on the remains. He helped her calm down and suggested that she walk through her day with him. That's when she realized that she had used the downstairs bathroom that day instead of her own office. Together with Benton and Marino, they headed downstairs and found that the bathroom's soap had the glitter goo that was found on the jumpsuit and the victims' bodies. Scarpetta wondered if the killer had a metabolic disorder that left him with a strong smell, making him wash his hands obsessively.
At present, Marino confronted Matt and began punching him. Lucy and Fruge arrived and pulled Marino off of him. Matt explained that he had read an article about Gwen's work in 3D printing organs and had met her at a bar. They went to her house but nothing happened. Matt was more interested in the possibility of fully functioning synthetic organs - and using them to bring his dead wife back to life.
At her office, Scarpetta instructed Maggie to gather all the paperwork for the Cammie Rammada case. At that moment, FBI officers arrived at her office and flew her by helicopter to a remote location. She was surprised to see Benton waiting to welcome her.
