Chase Episode 1.12 Narco, Part 1

Annie and her team huddle outside a mansion where a quinceanera is in progress. Pablo Cordova makes a speech in honor of his 15-year-old niece Eva, and manages to charm his wife Isabella, their son Pablo, and his sister-in-law Maria. Suddenly Annie busts into the soiree with a warrant for Pablo's arrest. As the agents take Pablo away, Isabella looks on in shock. It's two months later. In a hotel room, Max - one of the attendees of the quinceanera - talks to U.S. Marshal Alex Harding. It's clear Max ratted on his supposed friend Pablo and continues to give information to the Marshals about the drug kingpin. Suddenly Hector Torres - Pablo's right hand man - charges in with Isabella. They kill Alex and capture Max, setting him on fire.

Marco hosts a backyard barbeque. Jimmy chats with DEA agent Felix Perez about their shared relief that Pablo's trial is finally underway. Marco joins the conversation and pals around with Perez. Marco and Perez go way back; they worked together as undercover agents for six years before Marco joined H.E.A.T. Meanwhile across the party, Jimmy's girlfriend Natalie tells Annie that she's planning on proposing to Jimmy! Moments later, Natalie makes good on her promise and asks Jimmy to marry her. Their intimate moment is interrupted when the entire gang gets word that Isabella and Hector killed Max - the key witness in the case against Pablo. Max knew the financial side of Pablo's financial operation, so his death is a huge blow to the case. Perez insists that a Marshal must have tipped off Isabella about Max, but Annie and Jimmy say it's impossible.

Perez and Assistant U.S. Attorney Dan O'Neil explain the details of the Cordova case to the H.E.A.T. gang. Isabella killed Max personally to send a message to rival drug cartels: with Pablo behind bars, Isabella is the new boss in town. Annie must capture Isabella and find out who leaked Max's whereabouts to the vicious killers. Annie decides to question Isabella's son Matthew and her sister Maria. At a flower shop, Isabella asks her son Matthew to collect his things because it's time to leave. Before exiting, Isabella turns to her sister Maria and says she has to ask a favor. Moments later, Annie shows up to question Maria. Maria refuses to talk, even when Annie threatens to charge her with being an accessory to Max's murder. Annie realizes that Maria has traded her car for Isabella's. It's time to track down Isabella!

On a Houston road, Officer Tillman pulls over Isabella and Matthew. Isabella calmly makes a phone call before exiting the car. Then Tillman's phone rings. Isabella tells the officer to answer his phone, saying it's the most important call he'll ever receive. Tillman takes the call and lets Isabella and Matthew drive off! Back at H.E.A.T., Annie asks Tillman why he let Isabella go. Tillman says that a mysterious caller threatened to murder his wife and children. He had no choice but to let Isabella go. Realizing that someone is leaking information to Isabella (in this case, about an officer's family), Annie decides to keep the investigation top secret. With Max dead, Pablo Cordova will have to be set free. Annie intends to follow Cordova in hopes that he'll lead her to his wife Isabella.

Perez shares details of the case against Cordova with Marco. Marco sees a surveillance photo of Cordova talking to Jose Sanchez, a criminal Marco recognizes from his days as an undercover agent. Marco intends to get Sanchez to talk. At a court hearing, Cordova is about to be dismissed when Agent Perez interrupts to say that a new witness has come forward. The judge grants the prosecution a 48-hour continuance. After court adjourns, Annie lets Pablo know that she's hot on his wife Isabella's trail. Pablo says that if anything happens to Isabella, he'll blame Annie. Annie looks on, unafraid.

Marco interrogates Sanchez, threatening to tell Cordova about his past as a secret informant unless he shares details about Cordova's drug operation. Sanchez cooperates, telling Marco that the Cordova ring has drug distribution centers secreted within nearby ranches. One ranch in particular has a landing strip, allowing drug drop-offs from airplanes. This is one major illegal operation! At the ranch, Isabella tells Matthew to board a plane and leave the country. Matthew realizes for the first time that his dad is a no-good drug dealer. As Isabella walks away, she gets a phone call telling her that another witness has come forward. Moments later the H.E.A.T. team arrives and stops the plane from taking off with Matthew. Isabella is long gone.

Annie questions Matthew but he won't talk. Sadly, he's become like his parents, arrogant and dismissive. Seeing his fake passport and a suitcase of stolen cash, Annie arrests Matthew for obstruction of justice. She takes Matthew's cell, hoping Isabella will call to see if he landed safely. Daisy talks to Brian Bouffton (aka "Bouff"), a technician working on the Cordova case. Bouff says a call came into Matthew's cell from an intersection in Sugarland. Daisy thanks Bouff for his help. At the Sugarland intersection, Isabella and Hector watch a black SUV pick up the new witness in the case against Pablo Cordova. Isabella sets off an explosive and the SUV goes up in flames. Isabella walks up to the wreckage and sees the body of the rat: it's her sister Maria!

As Maria struggles to stay alive, Isabella asks her sister why she ratted on Pablo. Maria reveals that she's pregnant with Max's baby. Maria turned on Pablo once she found out he killed Max. Isabella ruthlessly shoots and kills her sister. Annie and her team arrive on the scene to realize that someone on the inside is still tipping off Isabella. Marco blames Agent Perez, who sneers, asking why Marco doesn't just shoot him. Marco explodes in a rage. Later he explains to Jimmy that Perez was making reference to his painful past. When Marco worked as an undercover DEA agent, he found out his partner was a rat and killed him. After confessing his dark past to Jimmy, Marco storms off.

At an airport, Isabella buys a ticket to Santo Domingo. Back at Maria's murder scene, Annie isn't convinced that Perez is the snitch. She notices a tracking device affixed to Perez's suitcase and makes a startling realization: Assistant U.S. Attorney Dan O'Neil used Perez to lead him to the new witness. Then O'Neil shared the secret information with Isabella! O'Neil's the mole - not Perez! Annie storms into O'Neil's office and places him under arrest. Annie then uses O'Neil's phone to call Isabella. Annie tells Isabella that she's got Matthew and he's going to face the death penalty unless his mother returns to take his place. Looks like Isabella's not boarding that flight after all.

Outside the courthouse, Cordova's lawyer tells the media that the mysterious second witness has disappeared and his "innocent" client will go free. Marco interrupts the celebration with a handcuffed Matthew. Marco tells Pedro that his son is going to be charged as an accessory to murder. Before Pedro can react, Isabella darts out of a nearby taxi and tells Annie to let Matthew go. Isabella is going to take her son's place. Suddenly shots ring out. Unseen shooters kill Isabella and Matthew. Annie's shot too, but thankfully she's wearing a bulletproof vest. Jimmy shoots another assassin who's about to kill Pablo. Pablo looks at Annie with rage: he clearly blames her for the death of his family.

Later that night Jimmy checks on Annie, who's still healing from the gunfight at the courthouse. Jimmy says the assassins were members of the rival Satevo drug cartel. This has turned into an all out bloodbath and Annie's still in danger. After all, Pablo threatened Annie and Hector's still on the loose. Annie appreciates Jimmy's concern but says she'll be all right. Everyone is winding down after a chaotic day. Marco looks at a photo of the partner he had to kill. Jimmy climbs into bed with Natalie and slips an engagement ring onto her finger. But for Annie however, the nightmare's about to begin. An SUV slams into her car at an intersection, and Hector and his thugs descend upon Annie. They tie her up and duct tape her mouth.
