In episode 8, it is revealed that Chris, whose real name is Alexandra, was once a Russian spy who faked her death to escape the agency. She did this not only for her own safety but also to protect her former handler and lover, Inga, from being killed if Chris failed. This backstory is explored as Chris is kidnapped by old associates and held captive on an Arctic oil rig in the Barents Sea.

Chris and Inga share a complicated past as former lovers and colleagues in the Russian spy agency. Inga was Chris's handler, and their relationship ended when Chris defected and faked her death. Despite their past, their reunion in the episode is tense and unfriendly, reflecting the dangerous and unforgiving nature of their work.

The Lazarus team, including Axel, Leland, Doug, and Eleina, work together to rescue Chris from captivity on the Arctic oil rig. Their mission to save her is a central focus of the episode, highlighting their teamwork and determination.

The episode is set primarily on an oil rig located in the Barents Sea in the Arctic. Chris wakes up there as a prisoner, and the harsh, freezing environment adds to the tension and danger of the situation.

Episode 8 deepens the character development of Chris by revealing her past and motivations, which had been largely unexplored before. It also escalates the stakes as the team races against time to rescue her, setting up a collision course with the season finale where the lethal side effects of the drug Hapna become more imminent.
