Biography
Kara is a former Russian spy and the ex-lover of MI6 agent Adam Lawrence.

Kara has complex ties to her Adam and the SVR, Russia's spy agency. For many years, she has been playing with Adam's career for her own personal gain. She was the one who gave Adam intel on the planned attack on the British embassy in Baku. Her involvement in Sir Martin Angelis's assassination attempt makes her a target, but she might be able to use her relationship with Adam to get away with it.

Throughout Treason
Adam Lawrence, the deputy chief at MI6, is made the interim chief when his boss and longtime friend, Sir Martin Angelis is poisoned by Kara, Adam's ex-lover and a former Russian spy.

Later, Adam is approached Kara, who asks him to help her. They previously worked together in Baku, when Kara gave Adam information about the planned attack on the British embassy. Adam refuses.

When Adam's daughter, Ella Lawrence, is kidnapped, Kara finds information on Ella's location and goes to rescue her with Adam. However, Kara kidnaps Ella and takes her to another location. Kara blackmails Adam into searching for a file about Audrey Gratz at Martin's home. Kara returns Ella once he hands over the file. While searching for files in Martin's home, Adam comes across a file about himself. CIA was suspicious that Adam had been compromised, due to his intel on the planned attack.

Unbeknownst to Adam and Kara, Adam's wife, Maddy De Costa, has been following them and passing information about them to her friend in the CIA, Dede Alexander. Maddy is worried about the safety of her family and shares these concerns with Dede. They previously served in the military together. Dede gave Maddy a pen that could record sounds within 10 metres, which she used to record Adam's phone call with Kara. Later, Maddy followed Adam when he met up with Kara, and she took a photo of the two. The recording and the photos were handed to Dede.

Maddy plants a gift card with a tracker in Adam's wallet to help the CIA track him. They follow him when he meets with Kara again. Maddy joins Dede in the van while they track Adam. She overhears Adam's conversation with Kara, where she tells him it was the CIA who kidnapped Adam. Maddy is angry at her friend for betraying her. The two argue outside the van, and are spotted by Adam.

Adam goes home and takes his kids to Martin's house. He tells his wife, Mary, that he and Maddy fought, so they needed a place to stay. While Mary is distracted playing piano with the kids, Kara sneaks around the basement searching for a file about Baku, as she needs to know who killed the 5 men who worked for her in Baku. She had promised these men safety, so she owed it to their families to tell them who had killed them.

When Martin returns home from the hospital, he confronts Adam regarding his relationship with Kara. He shows him a file, and tells Adam he will be going to jail.
